Answer 2

The saving is 20%.

Given: 1 kilogram of wall putty costs Rs 30. A 10

kilogram pack of putty costs Rs 240.

To find: We have to find the percentage of savings in buying a 10-kilogram pack.

Solution:

1 kilogram of wall putty costs Rs 30.

So, 10 kilograms of wall putty will cost 30×10=300 rupees.

A 10-kilogram pack of putty costs Rs 240.

Thus in buying the 10 kilograms bag of wall putty one can save 300-240=60 rupees.

Thus the percentage of profit will be-

$\frac{60}{300} \times 100 = 20\%$

One can save 20% by buying a 10

kilogram pack.

So, the saving is 20%.
