Question

In a drum of 100ltr oil, 3 containers of 10 ltr, 6 containers of
5 ltr and 10 containers of 3 ltr can be filled then how
much oil is left in the drum and how many containers
of 2 ltr can be filled in remaining oil ?
​

Answer 1

Answer:

3 containers of 10 ltr oil=(3×10)= 30ltr oil

6 containers of 5 ltr oil=(6×5) = 30ltr oil

10 containers of 3 ltr oil=(10×3)=30ltr oil

we know that, the drum can be fill up to 100ltr oil only

now drum is filled up to (30+30+30)=90ltr only

left space =10ltr

10÷2=5, so only five containers of 2ltr oil can be pour in it.
