Question

MR .GOPINATH IS 30 YEARS OLDER THAN IS SON . IF IS AGE EXCEEDS TWICE HIS SON'S AGE BY 11 YEARS , FIND THEIR AGE'S ?

Answer 1

let g be gopinaths age and s be sons age

g= s + 30
g- s = 30. **eqn i

g = 2s + 11
g- 2s = 11. **eqn ii

eqn i - eqn ii:
s = 19

Substituting in eqn i:
g - 19 = 30
g = 30 + 19
= 49

Gopinath is 49 yrs old
son is 19 yrs old
