Mr. Ahmed earns 75,000 per month, his saving and expense ratio is 1:3. i. calculate the saving amount and ii. percentage of saving
Correct Answer
C. I. 18,750, ii. 25%
Explanation
The saving and expense ratio of 1:3 means that for every 1 unit of income Mr. Ahmed saves, he spends 3 units. Since Mr. Ahmed earns 75,000 per month, his total expense would be 3 times his saving. Therefore, his saving amount would be (1/4) * 75,000 = 18,750. To calculate the percentage of saving, we divide the saving amount by the total income and multiply by 100. Therefore, the percentage of saving would be (18,750/75,000) * 100 = 25%.

A batsman scored 120 runs which included 4 boundaries and 7 sixes. What percent of his total score did he make by running between the wickets?
Correct Answer
A. 51.67%
Explanation
The batsman scored 120 runs, and out of those, 4 boundaries and 7 sixes account for 64 runs. To find the percentage of his score made by running between the wickets, we subtract 64 from 120, which gives us 56. Therefore, the batsman made 56 runs by running between the wickets. To calculate the percentage, we divide 56 by 120 and multiply by 100, resulting in 46.67%.

Two students appeared at an examination. One of them secured 9 marks more than the other and his marks was 56% of the sum of their marks. The marks obtained by them are:
Correct Answer
C. 42, 33
Explanation
Let's assume the marks obtained by the first student is x and the marks obtained by the second student is y. According to the given information, x = y + 9 and x = 0.56(x + y). By substituting the value of x from the first equation into the second equation, we get y + 9 = 0.56(y + 9 + y). Simplifying this equation, we get 1.56y + 15.84 = 2.56y. Solving for y, we find y = 24. Substituting this value back into the first equation, we get x = 33. Therefore, the marks obtained by the two students are 33 and 24.

In an election between two candidates, one got 55% of the total valid votes, 20% of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got, was:
Correct Answer
A. 2700
Explanation
In this election, 20% of the votes were invalid, which means that 80% of the votes were valid. Since one candidate got 55% of the total valid votes, the other candidate must have received the remaining 45% of the valid votes. To find the number of valid votes the other candidate got, we can multiply the total number of votes by 80% (to find the valid votes) and then multiply that by 45% (to find the votes received by the other candidate). Therefore, the number of valid votes that the other candidate got is 7500 * 0.8 * 0.45 = 2700.

ABC company earns revenue 500,000 and suffers a 12% loss. Calculate the total expense of ABC company
Correct Answer
C. 560,000
Explanation
If ABC company earns revenue of 500,000 and suffers a 12% loss, we can calculate the total expense by subtracting the loss from the revenue. A 12% loss on 500,000 would be 60,000 (12% of 500,000). Therefore, the total expense would be the revenue minus the loss, which is 500,000 - 60,000 = 440,000. However, none of the given options match this calculation, so the correct answer is not available.

Rs. 5000 suit is on sale for 25% off. How much is the suit after the discount?
Correct Answer

A buyer purchased a gift for Rs 550. The profit margin of the seller was 10%. Before reaching home buyer changed his idea and exchange the same gift with different colors and paid an extra amount of Rs. 50 for the exchange. Find the seller's profit and profit percent.
Correct Answer
C. 20%
Explanation
The buyer initially purchased the gift for Rs 550, and the seller's profit margin was 10%. This means that the seller sold the gift for 110% of its cost price. Therefore, the cost price of the gift for the seller was Rs 550/1.10 = Rs 500. After the exchange, the buyer paid an extra amount of Rs 50, which means the new selling price for the seller is Rs 550 + Rs 50 = Rs 600. The profit for the seller is the difference between the selling price and the cost price, which is Rs 600 - Rs 500 = Rs 100. The profit percent is calculated as (profit/cost price) * 100, which is (100/500) * 100 = 20%.
