Question 67

A fruit seller has a sale of ₹10,435, ₹9,927,₹10,855 ₹10,230 and ₹9,562 for five consecutive months.How much sale (in ₹) must he have in the sixth month so that he gets an average sale of ₹10,500?

Solution

As we know,

Average = $$\frac{Sumofobservation}{total\ number\ of\ observation}$$

Let the sale of 6th month be x

Average = $$\frac{\left(10435+9927+10855+10230+9562+x\right)}{6}=10500$$

= $$51009\ +\ x=63000$$

x = 11991

Hence, option D is correct.
