vickey bought 15 notebook for rs.240.how many notebook can be bought for ra.160?​

Answer 1

Answer:

10 notebooks can be bought for Rs. 160

Step-by-step explanation:

Here the cost of 15 notebooks is given to be Rs.240

We have to find the number of notebooks that can be bought for Rs.160

Let the number of notebooks be x

Now, as the amount decreases the number of notebooks that can be bought will also decrease

So, we will use direct proportion

cost of 15 notebooks = 240

cost of x notebooks = 160

                      240x = 15 × 160

                      240x = 2400

                             x = 2400/240

                             x = 10
