Answer:
Let the numbers are 3x and 5x
increased by 5 then
(3x+5)/(5x+5)=2/3
3(3x+5)=2(5x+5)
9x+15=10x+10
5=x
x=5
original numbers are 3*5 =15 & 5*5=25
hope it helps

Question:-
Two numbers are such that the ratio between them is 3 : 5. If each is increased by 5, the ratio between the new numbers so formed is 2 : 3. Find the original numbers.
Answer:-
The two numbers are 15 and 25 respectively.
Solution:-
Ratio of two numbers = 3 : 5
Let the first number be 3x
and the second number be 5x
The new numbers when increased by 5,
The first number = 3x + 5
The second number = 5x + 5
Ratio of the new numbers = 2 : 3
According to problem,
Cross multiplying the terms.
Hence, the value of x is 5.
Therefore,
The first number => 3 × 5 = 15
The second number => 5 × 5 = 25
