Answer 1

Answer:

cost of 36 cards = ₹5.40 and,

In ₹45 we can buy = 300 cards

Step-by-step explanation:

here, Cost of 15 cards = ₹2.25

so, cost of 1 card = ₹2.25/15

∴ cost of 36 cards = ₹2.25/15 * 36

                              = ₹5.40

now, In ₹0.15 we can buy 1 card

so, In ₹45 we can buy = 45/0.15

                                     = 300 cards

hope it will help you.
