Vehicles and seats

In your book, Maths Mela (Chapter 13, The Transport Museum), we find how many people can travel in a group of vehicles when every vehicle is full. We multiply the number of vehicles by the number of people one vehicle carries.

Here is how many people each vehicle carries: a cycle carries 1 person, an auto carries 3 passengers, a car carries 4, a minibus has 20 seats, and an aeroplane has 152 seats.

So 75 cycles carry 75 × 1 = 75 people. 52 autos carry 52 × 3 = 150 + 6 = 156 people. 103 cars carry 103 × 4 = 400 + 12 = 412 people. 20 minibuses carry 20 × 20 = 40 tens = 400 people.

30 aeroplanes carry 30 × 152 people. 30 is 3 tens, so this is 152 × 3 tens. 152 × 3 = 456, so it is 456 tens = 4560 people.
