What should be added to each term of the ratio 5 : 11 so that the ratio becomes 3 : 5?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4.
Let the term added = x
So, (5 + x)/(11 + x) = 3/5
⇒ 25 + 5x = 33 + 3x
⇒ 2x = 8
⇒ x = 8/2 = 4
Therefore, the required term is 4.
