Question

The ratio between the present age of P and Q is 3:4 respectively. If Q's present age is 20 years, what will be the ratio of the ages after 5 years

Answer 1

So the ratio is 3:4 age of p to the age of q
Q present age is 20
Take 4x=20
=x=5

Age of p =3x
=3×5=15

Age of p after 5 years is 20
Age of q after 5 years is 25


Ratio =20:25
=4:5

Answer 2

$<b><I>HELLO !$
GIVEN÷

$<u>RATIOS</u>$
3:4
Let P age be 3x

And Q age be 4x

Q's present years=20

So, we know that Q present year2 also 4x

==>4x=20
==>x=5

Again we know that P age is 3x

so, $<b>REPLACED X</b>$

P's age =3×5
=15yrs

$<u>AFTER 5 YRs</u>$

P's age is =15+5=20
Q's years=20+5=25

$<b>AFTER 5 YEARS Ratio</b>$

20/25=4:5

So, after their age ratio is
$\red{\huge{4:5}}$
