Answer 2

Answer:

160 Rupees

Step-by-step explanation:

According to the information provided in the question it is given as

Cost of book= 200

20% off on this amount

We need to find the money to give to the shopkeeper after discount

Let first understand that this is a percentage based question as

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

Here  first we find  20% of 200

$\frac{20}{100} \times 200$

converting the lowest term for finding the answer

( As both 100 and 200 are divisible by 100)

$=20\times 2\\=40 rupees$

Now this is the deducted amount after discount

Cost of book after discount of 20% =actual amount - 20% amount

 Putting the values we get the answer

$=200 - 40\\= 160 rupees$
