A bag contains Rs. 4100 in the form of Rs. 5, Rs. 2 and Rs. 1 coins. The number of coins are in ratio 4: 6: 9. So, find the number of 1 Rs. coins.
Correct Answer
C. 900
Explanation
Let's assume the number of Rs. 5 coins is 4x, the number of Rs. 2 coins is 6x, and the number of Rs. 1 coins is 9x.
The total value of the coins can be calculated as follows:
4x * 5 + 6x * 2 + 9x * 1 = 20x + 12x + 9x = 41x
We are given that the total value of the coins is Rs. 4100, so we can set up the equation:
41x = 4100
Solving for x, we find that x = 100.
Therefore, the number of Rs. 1 coins is 9x = 9 * 100 = 900.
Hence, the correct answer is 900.

The ratio of cooper and Tin in a 63kg alloy is 4: 3. Some amount of copper is extracted from the alloy and the ratio becomes 10: 9. How much copper is extracted.
Correct Answer
A. 6 kg
Explanation
The initial ratio of copper to tin in the alloy is 4:3, which means that for every 4 parts of copper, there are 3 parts of tin. After some copper is extracted, the new ratio becomes 10:9. This means that for every 10 parts of copper, there are 9 parts of tin. Since the amount of tin remains constant, we can compare the change in the amount of copper. The change in the ratio is 10-4 = 6 parts of copper. Since each part represents 1 kg, the amount of copper extracted is 6 kg.

A shopkeeper earns a profit of 12% on selling a book at 10% discount on the printed price. The ratio of the cost price to the printed price of the book is?
Correct Answer
A. 45 : 56
Explanation
The shopkeeper earns a profit of 12% on selling the book at a 10% discount on the printed price. This means that the selling price is 112% of the cost price. Let's assume the cost price of the book is 100. The selling price would then be 112. Since the selling price is at a 10% discount, the printed price would be 100% of the selling price, which is 112. Therefore, the ratio of the cost price to the printed price is 100:112, which simplifies to 45:56.

An amount of Rs. 735 was divided between A, B & C. If each of them had received Rs. 25 less. Their shares would have been in the ratio 5: 4: 2. Find the money received by A.
Correct Answer
A. 325
Explanation
If each person had received Rs. 25 less, the new ratio of their shares would be 5:4:2. Let's assume the original shares of A, B, and C were 5x, 4x, and 2x respectively. Therefore, the total amount divided would be 11x. Now, if each person received Rs. 25 less, their new shares would be (5x-25), (4x-25), and (2x-25) respectively. According to the given information, (5x-25)/(4x-25) = 5/4. Solving this equation, we find x = 25. Therefore, A's share would be 5x = 5*25 = 125. But since each person received Rs. 25 less, A's actual share would be 125 + 25 = 150. Therefore, the money received by A is Rs. 325.
25.
If (a + b) : (b + c) : (c + a) = 3 : 4 : 5 and a + b + c = 17. Find C.
Correct Answer
A. 17/2
Explanation
Given that (a + b) : (b + c) : (c + a) = 3 : 4 : 5, we can assume that the sum of the three ratios is equal to the sum of the three variables, which is (a + b) + (b + c) + (c + a) = 2(a + b + c). Therefore, 2(a + b + c) = 3 + 4 + 5 = 12. Since a + b + c = 17, we can solve for C by substituting the value of a + b + c into the equation: 2(17) = 34. Therefore, C = 34/2 = 17/2.
26.
Find the third proportional of 12, 16.
Correct Answer
A. 64/3
Explanation
The third proportional of two numbers is a number that is in the same ratio to the second number as the second number is to the first number. In this case, the first number is 12 and the second number is 16. To find the third proportional, we can set up a proportion: 12/16 = 16/x. Cross multiplying, we get 12x = 16 * 16, which simplifies to 12x = 256. Dividing both sides by 12, we find that x = 256/12, which simplifies to 64/3. Therefore, the third proportional of 12 and 16 is 64/3.
27.
Find the ratio between the 3rd proportional of 4, 5 and the 4th proportional of 3, 6, 18.
Correct Answer
A. 25:144
Explanation
The ratio between the 3rd proportional of 4, 5 and the 4th proportional of 3, 6, 18 is 25:144. To find the 3rd proportional of 4 and 5, we multiply 5 by the ratio of the two numbers, which is 4/5. This gives us 20/5 = 4. Then, to find the 4th proportional of 3, 6, 18, we multiply 18 by the ratio of the three numbers, which is 3/6. This gives us 54/6 = 9. Therefore, the ratio between the two proportions is 4:9. Simplifying this ratio gives us 25:144.
28.
If a: b: c = 2 : 3 : 4. Find → (a + b)/c ∶ (b + c)/a.
Correct Answer
A. 5:14
Explanation
The given ratio of a:b:c is 2:3:4. To find (a + b)/c : (b + c)/a, we substitute the values of a, b, and c into the expression. (a + b)/c = (2 + 3)/4 = 5/4, and (b + c)/a = (3 + 4)/2 = 7/2. Simplifying these fractions, we get 5/4 : 7/2. To make the denominators equal, we multiply the first fraction by 2/2, resulting in 10/8 : 7/2. Simplifying further, we get 5/4 : 14/4, which is equivalent to 5:14.
29.
The product of two numbers is 225 and the ratio between them is 3: 5. Find the difference between both numbers.
Correct Answer
A. 2√15
Explanation
Let's assume the two numbers are 3x and 5x (since the ratio between them is 3:5). We are given that the product of these two numbers is 225, so we can write the equation 3x * 5x = 225. Solving this equation, we get x^2 = 15. Taking the square root of both sides, we get x = √15. Therefore, the two numbers are 3√15 and 5√15. The difference between them is 5√15 - 3√15 = 2√15. Hence, the correct answer is 2√15.

Rs. 4300 is divided between 45 persons in which men, women and children are included. The money received by men, women and children is in the ratio 12 : 15 : 16 while the money received by each is in the ratio 6 : 5 : 4. Find the number of men, women & children?
Correct Answer
A. 10,15,20
Explanation
The total ratio of men, women, and children is 12 + 15 + 16 = 43. To find the number of men, women, and children, we need to divide Rs. 4300 in the ratio of 12:15:16.
First, we find the value of 1 unit by dividing Rs. 4300 by 43: 4300/43 = 100.
Then, we multiply the value of 1 unit by the respective ratio for men, women, and children:
Men: 12 units x 100 = Rs. 1200
Women: 15 units x 100 = Rs. 1500
Children: 16 units x 100 = Rs. 1600
Now, we divide the amount received by each by the respective ratio of money received by each (6:5:4) to find the number of men, women, and children:
Men: Rs. 1200 / 6 = 200
Women: Rs. 1500 / 5 = 300
Children: Rs. 1600 / 4 = 400
Therefore, the number of men, women, and children is 10, 15, and 20 respectively.

A man has to cover a distance of 6 km in 45 min. If the covers one-half of the distance in 2/3rd time, what should be his speed to cover the remaining distance in the remaining time?
Correct Answer
A. 12 km/hr
Explanation
The man covers one-half of the distance in 2/3rd of the time, which means he covers 3 km in 30 minutes. Since he has covered 3 km in 30 minutes, he has 15 minutes remaining to cover the remaining 3 km. To find his speed, we divide the remaining distance (3 km) by the remaining time (15 minutes), which gives us a speed of 12 km/hr. Therefore, the correct answer is 12 km/hr.

Two man A and B start walking from a place X at 4(1/2) km/hr and 5(3/4) km/hr, respectively. How many km apart will they be at end of 3(1/2) hr, if they are walking in the same direction?
Correct Answer
C. 4(3/8) km
Explanation
The distance covered by A in 3(1/2) hours is 4(1/2) * 3(1/2) = 15(3/4) km. The distance covered by B in 3(1/2) hours is 5(3/4) * 3(1/2) = 20(5/8) km. As they are walking in the same direction, the distance between them will be the difference between the distances covered by A and B, which is 20(5/8) - 15(3/4) = 4(3/8) km.
33.
A motorboat covers a certain distance downstream in 6 hrs but takes 8 hrs to return upstream to the starting point. If the speed of the stream be 6 km/hr, find the speed of the motor boat in still water.
Correct Answer
C. 42 km/hr
Explanation
The speed of the motorboat in still water can be found using the concept of relative speed. Let the speed of the motorboat be x km/hr.
When the motorboat is moving downstream, it gets an additional boost from the speed of the stream, so its effective speed becomes (x + 6) km/hr.
Similarly, when the motorboat is moving upstream, it has to overcome the speed of the stream, so its effective speed becomes (x - 6) km/hr.
We know that distance = speed × time.
Given that the distance covered downstream is the same as the distance covered upstream, and the time taken downstream is 6 hours while the time taken upstream is 8 hours, we can set up the following equation:
(x + 6) × 6 = (x - 6) × 8
Simplifying this equation, we get:
6x + 36 = 8x - 48
Rearranging and solving for x, we find:
2x = 84
x = 42
Therefore, the speed of the motorboat in still water is 42 km/hr.

Anand travelled 300 km by train and 200 km by taxi. It took him 5 hrs and 30 min. However, if he travels 260 km by train and 240 km by taxi, he takes 6 minutes more. The speed of the train is:
Correct Answer
A. 100 km/hr
Explanation
Let the speed of the train be x km/hr and the speed of the taxi be y km/hr.
Using the formula time = distance/speed, we can set up the following equations:
300/x + 200/y = 5.5
260/x + 240/y = 5.5 + 6/60 = 5.6
By solving these equations, we find that x = 100 km/hr. Therefore, the speed of the train is 100 km/hr.
35.
Two trains are 35 m apart and running in same direction with speeds 30 km/hr and 45 km/hr, respectively. If they cross each other in 5 minutes then what is the total length of both the trains?
Correct Answer
C. 1215 m
Explanation
The total length of both the trains can be calculated by finding the relative speed between the two trains and multiplying it by the time it takes for them to cross each other. The relative speed can be found by subtracting the speed of the slower train from the speed of the faster train. In this case, the relative speed is 45 km/hr - 30 km/hr = 15 km/hr. Converting this to m/s, we get 15 km/hr * (1000 m/1 km) * (1 hr/3600 s) = 4.17 m/s. The time it takes for them to cross each other is given as 5 minutes, which is 5 * 60 = 300 seconds. Multiplying the relative speed by the time, we get 4.17 m/s * 300 s = 1251 m. However, we need to subtract the initial distance between the two trains, which is 35 m. Therefore, the total length of both the trains is 1251 m - 35 m = 1216 m.
