Heyyyy mate
here is your answer..
given two numbers are in ratio= 7:11
let number= X
first number=7x
and second number=11x
according to question,
7x/11x
so, we will now add 7 both
7x+7/11x+7=2/3
3(7x+7)=2(11x+7)
21x+21=22x+14
21x-22x=14-21
-x=-7
after cancelling(-)
we got X= 7
so the number is 7
hope it help you

Answer :-
49 and 77.
Explanation :-
Given :-
Two numbers are in the ratio 7:11.
If 7 is added to each of the numbers, the ratio becomes 2:3.
To Find :-
Both the numbers.
Solution :-
Let,
First Number = 7x.
Second Number = 11x.
According to the Question,
➙ (7x + 7)/(11x + 7) = 2/3.
➙ 3(7x + 7) = 2(11x + 7).
➙ 21x + 21 = 22x + 14.
➙ 21x - 22x = 14 - 21
➙ -x = -7.
➙ x = 7.
Therefore,
First Number = 7x = 49.
Second Number = 11x = 77.
