Answer 1

Answer:

Mona's father present age is 36

Mona's present age is 12

Step-by-step explanation:

let ,Mona's father present age be X

Mona's present age is be Y

By first Condition,

$x - 3y = 0..........(1)$

by second condition,

$x - 2y = 12......(2)$

now, subtract equation( 1)and (2) we get

Y=12

now put y=12 in equation (1) we get

x=36

therefore,

Mona's father present age is 36.

Mona's present age is 12
