Question

A truck uses 20litres of ooil for 240km how many litres of oil will be needed for 1200km.

Answer 1

As the truck uses 20 liters for 240 km,
1km of the truck can be travelled by using 20/240 liters of oil.
Oil required to travel 1km =20/240
=1/12
Oil reqiured to travel 1200km =Oil required to travel 1km X 1200
=( 1/12) x 1200
=100
