Question

Cost of groundnuts is directly proportional to its weight. If cost of 5 kg groundnuts is ` 450 then find the cost of 1 quintal groundnuts. (1 quintal = 100 kg)

Answer 1

5 kg of groundnuts = 450 Rs.

1 kg of groundnuts = 450/50

= 90 Rs.

Now one Quintal of groundnuts = 100 x 90

= 9000 Rs.

Answer 2

As per the data given in the question,

In the above question, it is given that,

If the cost of 5kg groundnuts is 450

 We have to find the cost of one quintal groundnut.

Here 5kg of groundnut$=450$

Thus the cost of 1kg of groundnut $=\frac{450}{5}\\=90$

Therefore one quintal of groundnut$=100kg$

The cost of one quintal of groundnut,

$=100\times 90\\=9000$

Hence the cost of one quintal groundnut is 9000.
