Question

(c) The ages of Ravi, his father and his grandfather are in the ratio of 2.5 8. The
sum of their ages is 150 more than twice the sum of the ratios of their ages.
Find the ages of the family members
​

Answer 1

Their age will be

2(2+5+8)+150=2x+5x+8x

30+150=15x

180=15x

x=12 years

Ravi=2x=2×12=24 years

Father=5x=5×12=60 years

Grandfather=8x=8×12=96 years

Answer 2

Answer:

Ravis age is 10 years

fathers age is 50 years

grand fathers  age is 80 years

step-by-step explanation:

let Ravis age be 2x

let Fathers age be 5x

let grandfathers age be 8x

2x + 5x +8x =150 + 2( 2x + 5x + 8x )

15x = 150 + 3x

x = 10

∴ Ravis age = 2x = 2.10 = 20

  fathers age = 5x = 5.10 =50

 grand fathers age = 8x = 8.10 = 80
