Question

The average of Leander; Mahesh and Sania is 37 years. The sum of ages of Leander and Mahesh is 80 years find the age of Sania?

Answer 1

Answer:

The age of sania is 31 years

Step-by-step explanation:

Formula used:

$Average=\frac{sum\:of\:observations}{number\:of\:observations}$

Let x, y and z be the ages of Leander, Mahesh and Sania reaspectively

Given:

Their average = 37 years

$\frac{x+y+z}{3}=37$

$x+y+z=111$............(1)

Also , x+y =80

using this in (1) , we get

80+z=111

z=111-80

z=31

$\therefore\:$The age of Sania is 31 years
