Answer 2

As per the data given in the question,

We have to determine that,

How much a man need if he want to buy 100 pens, if the cost of 1 pens is Rs. 10.

As cost of 1 pen = Rs. 10.

So, for finding the cost of 100 pens we need to multiply the number of pens with the cost of 1 pens.

So, cost of 100 pens will be

$=(100 \times 10) = Rs.\:1000$

Hence, he needs Rs. 1000 if he wish to buy 100 pens.
