Question

A house owner wants to get his house painted. He is told that this would require 45 kg of paint allowing 6% wasting. And if the paint is available in 4 kg tins only, the number of tins required for painting the house is ?

A) 12 B) 13 C) 11 D) 10

Answer 1

Answer:

C

Step-by-step explanation:

45-6°/°of 45

=42.3

Hence there are 4kg tins available...

No. Of tins = 42.3/4

=10.6

But no.of tins can't be in fraction therefore no.of tins = 11 ans

Answer 2

Step-by-step explanation:

Paint required =>45kg

6℅. Is waste in that

So,

Waste paint = 6/100*45=2.7 kg is waste

Only 4kg tins are

So,

Tins of paint =>45/4=11 and some more

So

We take it 12
