Question

A is half as old as B and B is half as old as C.The sum of their ages is 105 years.Find the ages of A,
B and C

Answer 1

hi

let the age of c be x

then b= 1/2x

a=1/2×1/2×x=1/4x

sum = 105 = x+1/2x+1/4x

105=4x+2x+x=7x/4

x=105×4/7=60

c= 60

b= 30

a = 15

Answer 2

age of c=x

b=1/2x

a=1/4 x

1/2x+1/4x+x=105

now find value of x and put it
