20

Therefore, Rehan is 20 years old

Answer 2

hey there!

Let  Rehan's age be 'x'

and Narim's age be 'y'

according to the question :

x = y -5 ---------------------(1)

x + y = 25--------------------(2)

Now put the value of x from (1) into (2) :

• (y-5) + y = 25
• y-5 + y =25
• 2y = 25+5
• y= 30/2

• y = 15

Hence , Narim's age = 15 yrs

_______________________________________________

from equation (2) :

• x + 15= 25
• x = 25-15
• x =10 yrs

Hence , Rehan's age  = 10 yrs
