Question

The number which bears the same ratio to (7/43) that (9/22) does to (5/11) is

  1. A. 61/430
  2. B. 63/430
  3. C. 63/431
  4. D. 61/431

Answer

Correct option: B - 63/430

We need a number x such that: x : (7/43) = (9/22) : (5/11). This means x/(7/43) = (9/22)/(5/11). Solving the right side: (9/22) divided by (5/11) = (9/22) x (11/5) = 99/110 = 9/10. So x = (7/43) x (9/10) = 63/430. Verification: 63/430 divided by 7/43 = (63/430) x (43/7) = 9/10, which equals (9/22)/(5/11). Confirmed: answer is 63/430.
