Question

If 10% of m is the same as 20% of n, then m : n is equal to:
1. 2 : 1
2. 1 : 20
3. 1 : 5
4. 1 : 10

Answer 1

Correct Answer - Option 1 : 2 : 1

Calculations:

From the question, it is given that

(10/100) × m = (20/100) × n

⇒ (1) × m = (2) × n

m/n = 2

m : n = 2 : 1

∴ m : n is equal to 2 : 1.
