Answer 2

Answer:

let, present age of mina is x years

and present age of nita is y years

so, x+y=31

3 years ago mina is (x-3) years and nita is (y-3)years

so,

x-3=4(y-3)

=> x-3=4y-12

=> x=4y-12+3

=> x=4y-9

so,

4y-9+y=31

=> 5y=31+9

=> 5y=50

=> y=8

so, x=31-8=23

present age of mina is 23 years and present age of nita is 8 years
