Question

Sachin ki ayu rahul ki ayu se 7 varsh kam hai? yadi unki ayu ka anupat 7:9 hai to sachin ki ayu gyat kijiye?

Answer 1

Answer:

sachin ki age=56years old

rahul ki age =63 years old

Explanation:

rahul ki age =x+7

sachin ki age =x-7

anupat=7/9

now question that

x-7/x+7=7/9

9(x-7)=7(x+7)

9x-63=7x+49

9x-7x=49+63

2x= 112

x= 112/2

x= 56

then sachin is 56 years old

and rahul is 56+7 =63
