During the first month of sales, a company sold 1,300,000
schepotkina [342]

The right answer is Option C.

Step-by-step explanation:

Given,

Smartphone sold = 1300000 units

Smartphones returned = 15%

No. of smartphones returned = 15% of smartphones sold

No. of smartphones returned =\frac{15}{100}*1300000

No. of smartphones returned = 0.15*1300000 = 195000 units

As sales and return rate remains same, therefore,

Returns in 6 months = 6*per month returns

Returns\ in\ 6\ months=6*195000=1170000\ units

1170000 units will be returned to the company during 6 months.

The right answer is Option C.
