Two numbers are in the ratio of 5 : 7. If 6 is added to each, the ratio becomes 3 : 4. Find the numbers.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 30, 42.
Let's assume the ratio of the two numbers = 5x : 7x
Now, according to the question;
⇒ (5x + 6)/(7x + 6) = 3/4
⇒ 20x + 24 = 21x + 18
⇒ x = 6
So, the numbers = 30, 42
