Raju purchases 10 pens for ₹150 and Manish buys 7 pens for ₹ 84. Can you say who got the pens cheaper?

Solution:

Let's use the concept of the unitary method.

From the given data in the question

Total number of pens purchased by Raju for ₹ 150 = 10 

So, the cost of 1 pen will be = 150 / 10 = ₹ 15

Also, the total number of pens purchased by Manish in ₹ 84 = 7 pens

So, the cost of 1 pen will be = 84 / 7 = ₹ 12

Thus, we observed that the total number of pens purchased by Manish is cheaper than Raju.
