Answer:
M = 36 year old
N = 28 years old
Step-by-step explanation:
here,
let the present age of M and N be 'x' and 'y' respectively.
By the first condition,
(x+12) = 3( y - 12)
x+12 = 3y - 36
x = 3y-48 ........ eqn (i)
and
By the second condition,
x= y+8 ........ eqn (ii)
now,
combining both the equations...
x = x
3y-48 = y+8 ( from i and ii )
2y= 56
y = 28
then , if y = 28
soo.. x= y+8
= 28+8
= 36
