Detailed Solution

Concep- In such types of questions find the number of seats in the executive class by solving the percentage. Then using simple subtraction, find seats in the chair car and proceed to solve the question.
Seats in Executive class

= 10 %

of total seats

= 10100 × 500 = 50

∴

Seats in Chair car

= 450

Total seats booked

= 85 %

500 = 85100 × 500 = 425

Total seats booked in Executive class

= 96 %

50 = 96100 × 50 = 48

∴

Seats booked in Chair car

= (425 − 48) = 377

Empty seats in Chair car

= 450 − 377 = 73

Hence, the correct option is 3.
