Total number of Compartments = 7.
Average number of passengers in eachcompartments = 15
total number of passenger in 7 compartment= 15 × 7 = 105.
For the least number of passenger in 7th compartment,we have maximum number of passenger in first 6compartments.
Maximum passenger in first compartment = 15.
Maximum passenger in second compartment = 14.
Maximum passenger in third compartment = 13.
Maximum passenger in fourth compartment = 12
Maximum passenger in fifth compartment = 11.
Maximum passenger in sixth compartment = 10.
total number of passengers in 6 compartment = 75.
∴ Min. number of passenger in 7th compartment = 105 – 75 = 30.
