Answer 2

Answer:

Explanation:The numbers are in the ratio 2:3.

Let the common ratio be x.

Therefore the numbers are 2x and 3x.

If 42 is added to both the numbers the ratio become 44:45.

Therefore, (2x + 42):(3x + 42)= 44 : 45

Therefore, 14x + 35 = 15x + 25

Therefore, x = 10

Thus, the numbers are 2x = 2 × 10 = 20 and 3x = 3 × 10 = 30.
