Question

If cost of 7 notebooks is Rs 42.35, then how many notebooks can be bought for Rs 112.80?​

Answer 1

Answer:

cost of 7 notebooks = Rs 42.35

then, cost of 1 notebook = Rs 42.35/7 = Rs 6.05

therefore, notebooks can be bought for Rs 112.80

= Rs 112.80/Rs 6.05

= 18.6446281

therefore, we can only buy 18 notebooks and [112.80-(6.05×18)]=3.9 Rs should be left.
