40 people were employed who could together make 60 toys in 8 hours, but 8 people left just before work was to begin. How many toys could then be made in 12 hours?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 72
Given, 40 people can make 60 toys in 8 hours
In 1 hour 1 people can make 60/(40 x 8) toys
⇒ 60/320 = 3/16 part of toy
Here, we need to find how many toys could be made in 12 hours when 32 people works together
× 32 x 12 = 72
Hence 72 toys can be made in 12 hours when 32 people works together
