Find two consecutive natural numbers whose sum is 125.

Answer»

Let the number = x 

Consecutive number of x = x + 1 

Given that, x + (x + 1) = 125 

⇒ 2x + 1 = 125 

⇒ 2x = 125 – 1 

⇒ 2x = 124

⇒ x = 124/2

x = 62 and x + 1 = 62 + 1 = 63 

∴ Required numbers are 62 and 63. 

Check: 

Numbers: 62, 63 

Sum = 62 + 63 = 125 

Hence verified.
