Show Answer
Answer:
Correct Answer: D
Solution:
- Passengers of airline A who travelled to Chennai
First quarter $ =10000 $
Second quarter $ =\frac{15000\times 100}{120}=12500 $
Third quarter $ =\frac{15000\times 100}{120}=12500 $
$ \therefore $ Percentage increase $ =\frac{12500-10000}{10000}\times 100 $
$ =\frac{250000}{10000}=25 $ %
