The number of passengers travelling to Chennai in the second quarter by the same airline is $120\%$ of that in the third quarter.

• A. $15\%$
• B. $18\%$
• C. $20\%$
• D. $25\%$
• E. $30\%$

Answer 1

The correct option is D $25\%$

Passengers of airline A who travelled to Chennai
First quarter $\Rightarrow 10000$
Second quarter $\Rightarrow 10000\times \frac{150}{100}=15000$
Third quarter $\Rightarrow \frac{15000\times 100}{120}=12500$
Percentage increase $=\frac{12500-10000}{10000}\times 100=\frac{250000}{10000}=25$
