Question

A grocer has a sale of rs. 5420, rs. 5660, rs. 6200, rs. 6350 and rs. 6500 for 5 consecutive months. Find the sale he should have in the sixth month, so that he gets an average sale of rs. 6000?

Answer 1

Answer:

Step-by-step explanation:

Suppose the sale of last month (6th) is = X;

By Taking the average of all the sales;

Average=$\frac{Total-sum-of-all-the-amounts}{Total-Num-Of-Months}$;

Average = 6000, given

6000 = $\frac{5420+5660+6200+6350+6500+X}{6}$;

by solving this we get;

6000*6 = 30130+X;

X = 36000-30130;

X = 5870; Is the sale of 6th (Last month)

Answer 2

Answer:

The correct answer is 5870

Step-by-step explanation:

Given,

A grocer has a sale of rs. 5420, rs. 5660, rs. 6200, rs. 6350 and rs. 6500 for 5 consecutive months.

To find,

To calculate the sale he should have in the sixth month so that he earns an average sale of rs. 6000.

Assume the sale of last month (6th) stands $=X$;

By bringing the average of all the sales;

Average $=\frac{\text { Total-sum }-o f-a l l-\text { the-amounts }}{\text { Total }N u m-O f-\text { Months }} ;$

Average $=6000$, given

$6000=\frac{5420+5660+6200+6350+6500+X}{6}$

by caluculating this we get;

$6000*6=30130+X$

$X=36000-30130 \text$

$X=5870$; Is the sale of 6 th (Last month)
