Step-by-step explanation:
Four year ago the ratio of Monu and Sheena is
M : S
8x : 4x
After four year
M : S
8x + 8 : 4x + 8
Sum of ages
8x + 8 + 4x + 8 = 46
16 + 12x= 46
x = 30/12
x = 15/6 => 5/2
Monu age after 4 yrs is (8*5/2 + 8) = 28
Sheena age after 4 yrs is (4*5/2 + 8) = 18
Ratio is 28:18 => 14:9
