Question

If a sales person sell electric appliance on an average of $6$ appliances per day for the first two weeks. The dot plot is drawn to find out how much he sold in first $13$ days. What is the minimum number of appliances he must sell on the ${14}^{th}$ day in order to reach his goal?

• A. $5$
• B. $6$
• C. $7$
• D. $8$

Answer 1

The correct option is D $8$

Average of two weeks $=6Appliance/day$

Total in two weeks $14\times 6=84$

Total appliances sold in $13days=(2\times 3)+(3\times 4)+(1\times 5)+(3\times 6)+(1\times 7)+(1\times 8)+(2\times 10)=76$

Appliances must be sold on $14thday=84-76=8$
