Question

If the cost of lo pens is to rupees then
What is the cost of 15 pens​

Answer 1

Answer: 3 rupees

Step-by-step explanation:

If cost of 10 pens is 2 rupees

Then cost of 1 pen = 2/10

                                = 1/5

1 rupee = 100 paise

2 rupees = 2x100 =200 paise

1/5 of 2 rupees = 1/5 x 200

                           = 20 paise

So cost of 15 pens = 20 x 15 = 300 paise

                                = 3 rupees
