Question

A certain number of trucks were required to transport 60 tons of steel wire from the tisco factory in jamshedpur. however, it was found that since each truck could take 0.5 tons of cargo less, another 4 trucks were needed. how many trucks were initially planned to be used?1) 10

Answer 1

Let x be the number of trucks

Initially,
x number of trucks would transport 60 tons of wire

Each truck could take 0.5 tons of wire

In total x + 4 trucks were needed to transport 60 tons of wire

A truck carrying 0.5 tons it would take 60/0.5 number of trucks which is 120

4 trucks could take 2 tons of wire

Thus initially 116 trucks were to be used 

Answer 2

Let x be the number of trucks

Initially,
x number of trucks would transport 60 tons of wire

Each truck could take 0.5 tons of wire

In total x + 4 trucks were needed to transport 60 tons of wire

A truck carrying 0.5 tons it would take 60/0.5 number of trucks which is 120

4 trucks could take 2 tons of wire

Thus initially 116 trucks were to be used
