A ferry can carry 24 buses or 36 cars at a time. If there are 18 buses on the ferry, how many cars can be loaded onto it?
সমাধান
সঠিক উত্তর: Option C
24 buses = 36 cars
or, 1 bus = 36 / 24 cars = 3 /2 cars
Ferry is loaded with 18 buses. Ferry has free space in terms of buses = (24 - 18) buses
= 6 buses
Now,
1 bus = 3 /2 cars
6 buses = 3*6 / 2 cars
= 18 / 2 cars = 9 cars
