Question

The average of two numbers is 62. If 2 is added to the smaller number, the ratio between the numbers becomes 1:2. The smaller number is:

• A. 60
• B. 30
• C. 84
• D. 40
• E. None of these

Answer 1

The correct option is D 40

Let, the numbers be x and y, $x<y$.
Then $x+y=124;\frac{x+2}{y}=\frac{1}{2}\Rightarrow y=2x+4$
Solving the above equations, we get
$y=84,x=40$
