Question

The ratio of two numbers is 2:5 and their original difference is 63.what is larger number.

Answer 1

let proportionality constant=x
first number =2x
second number=5x

according to question ,,
5x-2x=63
3x=63
x=21

hence
first number =42
second number=105
so,
larger number is 105

Answer 2

Given ratio = 2:5
Let the ratio be 2 x and 5 x.

Difference = 63.
=> 5 x - 2 x = 63

3 x = 63
x = 63/3
x = 21

larger number = 5 x = 5 × 21 = 105
