Answer 1

" Although there is a mistake in your question, you might be referring to this full question: if a dozen pens cost 42.00.how many pens can be bought for 87.50"

Now, it is given that cost of 1 dozen pens, that means 12 pens is Rs. 42

We have to find out the number of pens that can be bought for Rs. 87.50

12 pens = 42

1 pen = 42 / 12

        = 3.5

Now, we will find the number of pens that can be bought for Rs. 87.50

Rs. 3.5 = 1 pen

Rs. 87.5 = 87.5 / 3.5 pens

            = 25 pens

Hence, 25 pens can be bought
