Answer 1

Answer:

b) 36

Step-by-step explanation:

age of P is 3 times the age of Q

P3

after 12 years

3×12

=36.

Answer 2

Answer:

e none of these

Step-by-step explanation:

let p's present age be x years and q's present age be y years

According to question

x-12 =3 (y-12)

x-12=3y-36

x-3y=-24

and

2 (x+12)=3 (y+12)

2x+24=3y+36

3y-2x=12

-3y+x=-24

____________

-x=-12 (by elimination method)

x=12

so present age of p is 12 years
