There are three numbers. 5/7th of the first number is equal to 48% of the second number. The second number is 1/9th of the third number. If the third number is 1125, then find 25% of the first number?
Correct answer: D. 21
- A. 168
- B. 84
- C. 42
- D. 21
- E. None of these
Explanation
The third number is 1125, so the second is 1125 / 9 = 125. Then 48% of 125 = 60, so (5/7) of the first number is 60 and the first number is 60 x 7/5 = 84; 25% of it is 0.25 x 84 = 21, while option c, 42, is 50% rather than 25%.
