Question

Ganga father is 45 years old his
age is 5 years more than 2 times Ganga age what is Ganga age​

Answer 1

Age of father = 45

age of ganga = 2x + 5

according to question -

2x + 5 = 45

2x = 45 - 5

2x = 40

x = 40÷2

x = 20

hence, age of ganga is 20

Answer 2

let the age of child =x

after 5 years sum of age =x

2(x+5)=x+5*5

2x+10=5x+25

3x=15

x=5

ganga age is 5 years
