Question

kise class ky 25 bacho ka aaust bajan 30 kg hai if teacher ka bhi bajan samil kar liya jay to bajan 32 kg ho jata hai teacher ka bajan kya hai
​

Answer 1

let the sum of the mass of the 26 kids be 'x kg'

and mass of teacher be 'x kg'

so,

x/25=30

x=750 kg

if teacher mass is added then,

if teacher is also considered....then..

x+y/26=32

750+y=832

y=832-750=82 kg

(or)

if teacher is not considered .....

x+y/25=32

750+y=800

y=50
