Answer:-
Given:
Ratio of two numbers = 3 : 4
Let the numbers be 3x , 4x.
The ratio becomes 5 : 7 if 5 is subtracted from both the numbers.
According to the question,
→ (3x - 5)/(4x - 5) = 5/7
On cross multiplication we get,
→ 7(3x - 5) = 5(4x - 5)
→ 21x - 35 = 20x - 25
→ 21x - 20x = - 25 + 35
→ x = 10
Hence, the numbers are 3(10) = 30 and 4(10) = 40.
