Question

A product is made by fitting 3 components A, B and C, onto a base. It takes 1 worker 1 hour to fit 150 of component A OR 75 of B or 30 of C. Show that 6 workers take 2 hours 40 minutes to make 300 units of the product?

Answer 1

`6` workers will complete `300` units of the product in `2` hours and `40` minutes (shown).

Explanation:

To make `300` of component `A` will require `300/150=2`

worker-hours. To make `300` of component `B` will require

`300/75=4` worker-hours and to make `300` of component `C`

will require `300/30=10` worker-hours. Therefore To make `300`

units of product required worker hours is `2+4+10=16`

So `6` workers will complete the product in `16/6=2 2/3` hours

or `2` hours and `(2/3*60)= 40` minutes .

`6` workers will complete `300` units of the product in `2`

hours and `40` minutes [Ans]
