Question

Adarsh is three times as old as Priyanka . After 3 years he will be twice as old as Priyanka. Find their present age

Answer 1

Adarsh's age= 3x

priyanka's age=x

after 3 years.......

he will be twice old as priyanka

so,

$3x + 3 = 2(x + 3) \\ 3x + 3= 2x + 6 \\ 3x = 2x + 6 - 3 \\ 3x = 2x + 3 \\ 3x - 2x = 3 \\ x = 3$

Adarsh's present age=3x

=3×3=9

priyanka's present age=x

=3

Answer 2

Let Priyanka's age = X

then, Adarsh's age= 3X

after 3 years,

Priyanka age = x+3

Adarsh age = 3X+3

according to the question, after 3 years Adarsh age is twice than Priyanka's so

2(x+3)= 3x+3

2x + 6=3x+3

3x-2x=6-3

x=3

so, Adarsh present age is 3*3=9

and Priyanka age is 3
