Answer:
The age of Jamal is 8 years.
And the age of his father is 32 years.
Step-by-step explanation:
=> let the age of Jamal be x and his father's age be y
=> so , A.T.Q ,
x+y = 40....i)
Find the value of y from here , that's y = 40-x .....
Now, After 4 years ,
=> 3(x+4) = (y+4)
=> 3x+12 = y+4
=> 3x+8 = y ...ii)
putting the value of y in equation ii)
=> 3x+8 = 40-x
=> 3x+x = 40-8
=> 4x = 32
=> x = 8
now ,
=> y = 40-x
=> y = 40-8
=> 32
