Question

A grocer has a sale of Rs. 4212, Rs. 4164, Rs. 4728, Rs. 4626 for four
consecutive months. How much sale must he have in the fifth month so that he
gets an average sale of Rs.4800 ?​

Answer 1

Step-by-step explanation:

average = sum of sales/number of sales

here average=₹4800

let the sale of fifth month be x

sum of sales=4212+4164+4728+4626+x=17730

average sale=sum of sales/number of sales

4800=17730+x/5

17730+x/5=4800

17730+x=4800×5

17730+x=24000

x=24000-17730

x=₹6270
