Answer:
Raj is 27 yrs and Be is 14 yrs
Step-by-step explanation:
let the age of Raj be x and Ben be y
case_1
x + y =37
x = 37 - y
case_2
x - 5 = 2(y -5)
x-5 = 2y -10
37 - y -5 = 2y - 10
32 + 10 = 2y + y
42 = 3y
y = 14 yrs
now,
x = 37 - 14
x = 27
Let x and y be present age of Raj and that of Ben respectively.
1. x+y=37
2. x-5=2(y-5)
from 2
x-5=2y-10
x=2y-5
Sub x=2y-5 into 1
2y-5+y=37
y=14
put y=14 into x=2y-5
x=2(14)-5
x=23
Thus, present age of Raj and Ben are 23 and 14 respectively.
