According to the question,
Number of passengers travelled to Bangaluru by airline B.
In first-quarter
= 30,000 ? 15,000 = 15,000
It has been stated that in second-quarter number of passengers increases by 30%
Therefore, number of passengers travelled in second-quarter to Bangaluru by airline B
= Passengers travelled in first quarter/100 × Total increase
= 15,000/100 × 130
= 19,500
Now, Number of passengers travelled to Kolkata by airline B.
In first-quarter
= 25,000 ? 20,000 = 5,000
It has been stated that in second-quarter number of passengers increases by 40%.
Therefore, number of passengers travelled in second-quarter to Kolkata by airline B
= Passengers travelled in first quarter/100 × Total increase
= 5,000/100 × 140
= 7,000
The number of passengers going to Bangaluru and Kolkata in first-quarter by airline B
= 15,000 + 5,000 = 20,000
The number of passengers going to the same cities in second-quarter
= 19,500 + 7,000 = 26,500
Therefore, required percentage
= 20,000/26,500 × 100
= 75.47% ? 75% (approx.)
