Question

A man buys 1500 kg of groundnut. the pods weigh 60% of the total groundnut weight. the pods are crushed and they yield oil content of 27% of their weight while the rest of the crushed material is treated once again for oil. yielding 6% oil by weight. what is the total amount of oil obtained from the groundnut pods(approximately)?

Answer 1

The total amount of oil obtained from the groundnut pods is 282.42 kg.

Explanation

Total weight of groundnut is 1500 kg and the pods weigh 60% of the total groundnut weight.

So, the weight of the pods $=(1500*0.60)kg=900 kg$

The pods are crushed and they yield oil content of 27% of their weight. So, the amount of oil in first time crushing $=(900*0.27)kg=243 kg$

Now, weight of the rest of the crushed material $=(900-243)kg=657 kg$

This crushed material is treated once again for oil, yielding 6% oil by weight. So, the amount of oil in second time crushing $=(657*0.06)kg=39.42 kg$

So, the total amount of oil obtained from the groundnut pods $=(243+39.42)kg=282.42 kg$
