Step-by-step explanation:

Hii Mate ✌

GIVEN :-

Sum of both numbers = 80

Ratio of both numbers = 9:11

TO FIND :-

Both the numbers

SOLUTION :-

Let smaller number be a

and greater number be b.

Let common factor be y.

So,

a+b = 80 .....(1)

a/b = 9/11

a = 9y

b = 11y

From (1), we get

a+b = 80

=> 9y+11y = 80

=> 20y = 80

=> y = 80/20

=> y = 4

So,

First Number = a = 9y = 9×4 = 36

Second Number = b = 11y = 11×4 = 44

ANSWER :-

The two numbers are 36 and 44.

100% CORRECT ✔️✔️
