CBSE NCERT Solutions for Class 8 Maths Chapter 13:

Question-1:

If a box of sweets is divided among 24 children, they will get 5 sweets each. How many would each get, if the number of the children is reduced by 4?

Solution:

Each child gets = 5 sweets
24 children will get 24 * 5 = 120 sweets.
Total number of sweets = 120
If the number of children is reduced by 4, then children left = 24 – 4 = 20
Now each child will get sweets = 120/20
= 6 sweets

Solution:

Here number of winners and prize money are in inverse proportion because winners are increasing, prize money is decreasing.
When the number of winners are 4, each winner will get =100000/4 = Rs. 25,000
When the number of winners are 5, each winner will get =100000/5 = Rs. 20,000
When the number of winners are 8, each winner will get =100000/8 = Rs. 12,500
When the number of winners are 10, each winner will get = 100000/10 = Rs. 10,000
When the number of winners are 20, each winner will get = 100000/20 = Rs. 5,000
