Answer»

⇒ Average = sum of elements / number of elements

Given

There are 2500 raincoats, 1500 schoolbags and 1000 water bottles were ordered in a month. Out of this, 60% of raincoats, 75% of schoolbags and 80% of water bottles were sold out.

Number of sold raincoats =

= (60/100) × 2500

= 1500

Number of sold schoolbags =

= (75/100) × 1500

= 1125

Number of sold water bottles =

= (80/100) × 1000

= 800

The price of a raincoat, a schoolbag and a water bottle is Rs. 300, Rs. 400 and Rs. 120.

Total price of 300 raincoats = 300 × 1500 = Rs. 450000

Total price of 400 schoolbags = 400 × 1125 = Rs. 450000

Total price of 120 water bottles = 120 × 800 = Rs. 96000

Total price INCLUDING all three sold ITEMS =

= 450000 + 450000 + 96000

= 996000

Total number of items =

= 1500 + 1125 + 800

= 3425

Average income of that shop for that particular month.

= (996000/3425)

= 290.8

Average income of that shop for that particular month is Rs. 290.8
