Two numbers a and b are in the ratio 3 : 2 and their sum is 25. The value of a is?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 15
In the ratio 3 : 2 the sum of 25 is split into \(3+2=5\) equal parts, and a takes 3 of the 5 parts.
One part \(=25\div5=5\)
\(a=3\times5=15\)
