Answer 1

Answer:

Step-by-step explanation:

let boy age is X,sister age =y so according to statement X=2Y---(1)

now four year ago

(X-4)=3(Y-4)

(X-4)=3Y-12

so as we know X=2Y then,

2Y-4-3Y-12

2Y+8=3Y

8=3Y-2Y

8=Y

so her sister age is now 8 year and boy is twice of her age=2(8)=16 years ----hope it helps---
