Start the planA certain manufacturer sells its products to stores in 113 different regions worldwide, with an average (arithmetic mean) of 181 stores per region. If last year these stores sold an average of 51,752 units of the manufacturer's product per store, which of the following is closest to the total number of units of manufacturer's products sold worldwide last year?
A. 10^6
B. 10^7
C. 10^8
D. 10^9
E. 10^10
The OA is D.
Number of different regions = 113
Average of stores per region = 181
Average units sold per store = 51752
Total number of units of manufacturer's product sold worldwide last year = 131*181*51752
We should use estimation here
110 * 180 * 50,000
= 198 * 10^2 * 50,000
= 2 * 10^4 * 5* 10^4
= 10 * 10^8
=10^9
Answer D.
Has anyone another strategic approach to solve this PS question? Regards!
