Question

the sum of two natural numbers is 121 if one number is 10 times the other find the two numbers​

Answer 1

Let one no be x another no will be 10x and

x+10x=121

11x=121

x=121/11

x=11

Answer 2

Let the two no.s be 'x' and 'y'

Given, x = 10 × y                  → 1

x + y = 121

10y + y = 121         (From 1)

      11y = 121

         y = 121 ÷ 11

⇒ y = 11

x = 10y = 10 × 11

∴ x= 110

∴ The two no.s are 110 ad 11.
