Banking Exams Quant — Question 1783
Question
The ratio of two numbers is 5 : 8. If each is increased by 8, the ratio becomes 2 : 3. Find the smaller number.
- 40
- 48
- 64
- 32
Correct answer
A — 40
Explanation (English)
Let the numbers be 5x and 8x. (5x+8)/(8x+8) = 2/3 → 3(5x+8) = 2(8x+8) → 15x+24 = 16x+16 → x = 8. Smaller = 5×8 = 40.
