Question

Two numbers are respectively 20% and 50% more than a third number The ratio of the two numbers is

• A. 2 : 5
• B. 3 : 5
• C. 4 : 5
• D. 6 : 7

Answer 1

The correct option is C 4 : 5

Let the third number be x.
Then first number=120% of x=$\frac{120}{100}\times x=\frac{6x}{5}$
Second number=150% of x$\frac{150}{100}\times x=\frac{3x}{2}$
$\therefore$Ratio of first two number=$\frac{6x}{5}:\frac{3x}{2}=12x:15x=4:5$
