    • D.

      मनोहरता के आधार पर

    Correct Answer
    C. इन्द्रियों की सन्तुष्टि के आधार पर
    Explanation
    The passage states that external beauty can be easily understood and expressed, but when beauty is combined with character, it also evokes a sense of pleasure. While a beautiful object may only satisfy the senses, a charming object also delights the mind. The passage further explains that the word "sundar" (beautiful) is limited, while "manohar" (charming) is more comprehensive and extensive. In literature, even ordinary objects can appear special and enchanting, which is why they are called "manohar." Therefore, based on this explanation, the correct answer is "इन्द्रियों की सन्तुष्टि के आधार पर" (based on satisfaction of the senses).

    When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?

    • A.

      Rs. 21,000

    • B.

      Rs. 22,500

    • C.

      Rs. 25,300

    • D.

      Rs. 25,800

    Correct Answer
    C. Rs. 25,300
    Explanation
    The owner originally sold the plot for Rs. 18,700 but incurred a loss of 15%. To find the selling price at which the owner would gain 15%, we need to calculate the original cost of the plot. We can do this by dividing the selling price by (100% - loss percentage), which in this case is (100% - 15%) = 85%. Therefore, the original cost of the plot is Rs. 18,700 / 0.85 = Rs. 22,000. To gain 15% profit, the plot must be sold for 115% of the original cost, which is 115% of Rs. 22,000 = Rs. 25,300. Therefore, the correct answer is Rs. 25,300.

    • D.

      6

    Correct Answer
    A. 3
    Explanation
    The roots of a quadratic equation in the form ax^2 + bx + c = 0 can be found using the quadratic formula. In this case, we are given that the roots are in the ratio of 2:3.

    Let the roots be 2k and 3k.

    Using the quadratic formula, we can equate the discriminant to zero to find the value of b.

    The discriminant, b^2 - 4ac, is equal to (-5)^2 - 4(2)(b).

    Simplifying this expression gives 25 - 8b.

    Setting this equal to zero and solving for b gives b = 3.

    • B.

      Rs. 500

    • C.

      2000

    • D.

      None of these

    Correct Answer
    C. 2000
    Explanation
    The sum of money is distributed among A, B, C, and D in the ratio of 5:2:4:3. Let's assume the common ratio to be x. Therefore, A's share is 5x, B's share is 2x, C's share is 4x, and D's share is 3x. It is given that C gets Rs. 1000 more than D. So, 4x = 3x + 1000. Solving this equation, we get x = 1000. Therefore, B's share is 2x = 2 * 1000 = Rs. 2000.

    From a point P on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point P from the foot of the tower is:

    • A.

      149 m

    • B.

      156 m

    • C.

      173 m

    • D.

      200 m

    Correct Answer
    C. 173 m
    Explanation
    Given that the angle of elevation of the top of the tower from point P is 30º and the height of the tower is 100 m, we can use trigonometry to find the distance of point P from the foot of the tower. The tangent of an angle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the height of the tower (100 m) and the adjacent side is the distance of point P from the foot of the tower (x m). Therefore, tan(30º) = 100/x. By solving for x, we find that x = 100/tan(30º) = 173 m. Therefore, the distance of point P from the foot of the tower is 173 m.

    Two tailors X and Y are paid a total of Rs. 550 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?

    • A.

      Rs. 200

    • B.

      Rs. 250

    • C.

      Rs. 300

    • D.

      None of these

    Correct Answer
    B. Rs. 250
    Explanation
    Let's assume that Y is paid Rs. X per week. According to the given information, X is paid 120% of Y. So, X = 1.2Y. The total amount paid to both X and Y is Rs. 550. Therefore, X + Y = 550. Substituting the value of X from the first equation into the second equation, we get 1.2Y + Y = 550. Simplifying this equation, we find that 2.2Y = 550, which means Y = 550/2.2 = 250. Hence, Y is paid Rs. 250 per week.

    The H.C.F. of two numbers is 23 and the other two factors of their L.C.M. are 13 and 14. The larger of the two numbers is:

    • A.

      299

    • B.

      276

    • C.

      322

    • D.

      345

    Correct Answer
    C. 322
    Explanation
    The H.C.F. (Highest Common Factor) of two numbers is the largest number that divides both numbers evenly. In this case, the H.C.F. is 23. The L.C.M. (Least Common Multiple) of two numbers is the smallest number that is a multiple of both numbers. The L.C.M. has two additional factors, 13 and 14. To find the larger of the two numbers, we can divide the L.C.M. by the H.C.F. and multiply it by the smaller number. Therefore, 23 multiplied by the smaller number gives us 322, which is the larger number.

    A man on tour travels first 160 km at 64 km/hr and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:

    • A.

      35.55 km/hr

    • B.

      36 km/hr

    • C.

      71.11 km/hr

    • D.

      71 km/hr

    Correct Answer
    C. 71.11 km/hr
    Explanation
    The average speed for the first 320 km of the tour can be calculated by finding the total time taken to cover the distance and then dividing it by the total distance. The time taken to cover the first 160 km at 64 km/hr is 160/64 = 2.5 hours. The time taken to cover the next 160 km at 80 km/hr is 160/80 = 2 hours. Therefore, the total time taken to cover the first 320 km is 2.5 + 2 = 4.5 hours. The average speed is then calculated as 320/4.5 = 71.11 km/hr.

    A can do a piece of work in 4 hours; B and C together can do it in 3 hours, while A and C together can do it in 2 hours. How long will B alone take to do it?

    • A.

      8 hours

    • B.

      10 hours

    • C.

      12 hours

    • D.

      24 hours

    Correct Answer
    C. 12 hours
    Explanation
    Based on the given information, we can determine that A's work rate is faster than B's because A can complete the work in 4 hours while B alone takes longer. Additionally, A and C together can complete the work faster than B and C together, suggesting that A's work rate is also faster than C's. Therefore, B's work rate is the slowest among the three. Since A and C together can complete the work in 2 hours, and A alone takes 4 hours, we can deduce that C alone takes 2 hours to complete the work. Thus, B's work rate is equal to C's work rate, so B alone will take 12 hours to complete the work.

    A starts business with Rs. 3500 and after 5 months, B joins with A as his partner. After a year, the profit is divided in the ratio 2 : 3. What is B's contribution in the capital?

    • A.

      Rs. 7500

    • B.

      Rs. 8000

    • C.

      Rs. 8500

    • D.

      Rs. 9000

    Correct Answer
    D. Rs. 9000
    Explanation
    Since A starts the business with Rs. 3500 and B joins after 5 months, B's contribution is not mentioned in the question. However, we know that the profit is divided in the ratio 2:3. This means that B's contribution must be 3 parts out of the total of 2+3=5 parts. To find B's contribution in terms of capital, we need to multiply his share (3 parts) by the total capital invested (3500*12) and divide it by the total share (5 parts). Therefore, B's contribution in the capital is (3/5)*(3500*12) = Rs. 9000.

    • A.

      20 hours

    • B.

      25 hours

    • C.

      35 hours

    • D.

      Cannot be determined

    Correct Answer
    C. 35 hours
    Explanation
    Pipe A is the slowest among the three pipes. Since pipe B is twice as fast as A, it can fill the tank in half the time it takes for A. Similarly, pipe C, being twice as fast as B, can fill the tank in half the time it takes for B. Therefore, if pipe A takes x hours to fill the tank, pipe B will take x/2 hours, and pipe C will take (x/2)/2 = x/4 hours. Given that all three pipes working together can fill the tank in 5 hours, their combined rate is 1/5 of the tank per hour. Using this information, we can set up the equation (1/x) + (2/x) + (4/x) = 1/5 and solve for x. The solution is x = 35 hours, which means pipe A alone will take 35 hours to fill the tank.

    The length of a rectangle is halved, while its breadth is tripled. What is the percentage change in area?

    • A.

      25% increase

    • B.

      50% increase

    • C.

      50% decrease

    • D.

      75% decrease

    Correct Answer
    B. 50% increase
    Explanation
    When the length of a rectangle is halved and the breadth is tripled, the new length becomes 1/2 of the original length and the new breadth becomes 3 times the original breadth. The area of a rectangle is calculated by multiplying the length and breadth. Therefore, the new area can be calculated as (1/2) * (3 times the original breadth) = (3/2) * the original area. To find the percentage change in area, we can calculate the difference between the new area and the original area, which is (3/2) * the original area - the original area = (1/2) * the original area. This is equal to a 50% increase in the area.
