Step-by-step explanation:

rahul = x

rohit = y

x = 2y

2y+4 * y+4 = 160

solving this,

y = 6

Answer 2

let the Rohit age be X

let the Rahul age be 2X

according to question,

X + 2X ×4 = 160

X+8x = 160

9X = 160

X= 160/9

X = approx 17 (real 17.7777778)

hence, Rohit present age =17

and rohan present age = 34
