Answer 1

Hi there!
Here's the answer:

•°•°•°•°•°<><><<><>><><>°•°•°•°•°

Let Present age of Pranav = 4x
& Present age of Qureshi = 5x
(°•° Given thay their ratio of their ages = 4 : 5)

Five years ago,
Age of Pranav = 4x - 5
Age of Qureshi = 5x - 5

Given,
The Ratio of their ages = 7 : 9

=> $\frac{4x - 5}{5x - 5} = \frac{7}{9}$

=> 9(4x - 5) = 7(5x - 5)
=> 36x - 45 = 35x - 35
=> x = 45 - 35
=> x = 10

•°• Present age of Pranav = 4x = 40
& Present age of Qureshi = 5x = 50

Answer 2

Answer:

40 and 50 years

Step-by-step explanation:

Let the present age of Pranav be 4x

Let the present age of Qureshi be 5x

After 5 years ago the ratio of their ages was 7:9

ATQ,

4x-5/5x-5=7/9

=9(4x-5)=7(5x-5)

=36x-45=35x-35

=36x-35x=(-35+45)

=X=10

Hence, present age of Pranav=4x=4×10=40years,

present age of Qureshi is=5x=5×10=50years
