Question

If 9 years later age of b will be equal to the present age of
a.Sum of a's age 3 years later & b's age 4 years ago is 76.If c is half of the present age of b then what will be c's age after 10 year

Answer 1

Step-by-step explanation:

let the age of a= x

let the age of b= y

after 9 years

y+9=x

y=x-9------eq(1)

acc. to ques.

x+3+y+4=76

x+3+x-9+4=76

2x=78

x=39

putting in eq.(1)

y=30

it is given that age of c= y/2

c= 30/2= 15

after 10 yrs age of c= 15+10= 25
