Question

If 10% of a number is equal to 3/5 of another number, then what is the ratio of first number to second number?

A

6.

B

7.

C

5.

D

3.

Soln.
Ans: a

We have ${10A}/100 = {3B}/5$, which can be re-arranged to $A/{3 × 100} = B/{10 × 5}$, so the required ratio is (3 × 100) : (10 × 5), which is 6 : 1. So the answer is 6.
