Question

Cost of 5 pens is ₹ 60 and 15 pencils is ₹75. Find ratio of cost of 1 pencil​

Answer 1

Answer:

Cost of 1 pen is rupees 6

Answer 2

Solution!!

The concept of unitary method has to be used here. We have to find the cost of 1 pencil. The cost of 5 pens is also given but we will ignore that part because it has nothing to do with what is asked. The cost of 15 pencils is given.

→ Cost of 15 pencil = Rs 75

Now, we have to find the cost of 1 pencil. It will be less than the cost of 15 pencils so we will divide.

→ Cost of 1 pencil = Rs 75 ÷ 15

→ Cost of 1 pencil = Rs 5

Hence, we got the cost of 1 pencil which is Rs 5.
