Market share percentage is defined as (product purchase from particular company / total amount of purchase of product ) * 100
How to solve?
- Market share of all the vendors in Q1 2012:
Samsung : (40612.8/147020.2)*100 =27.62%
Apple : (33120.5/147020.2)*100 = 15.768%
LG = (4961.4/147020.2)*100 = 2.36%
Huawei Tech. : (5269.6/147020.2)*100 = 2.508%
ZTE : (4518.9/147020.2)*100 = 2.15%
- Market share of all the vendors in Q1 2013:
Samsung : (64740/210046.1)*100 = 30.82%
Apple : (38331.8/210046.1)*100 = 18.24%
LG : (10080.4/210046.1)*100 = 4.799%
Huawei Tech. = (9334.2/210046.1)*100 = 4.44%
ZTE = (7883.3/210046.1) *100 = 3.75%
- From above, It's clear that none of the five top vendors had a decrease in market share from Q1 2012 to Q1 2013.
- Increase in sales of Samsung from Q1 2012 to Q1 2013 = [tex]\frac{64740-40612.8 }{40612.8}[/tex] * 100 = 59.41% Hence statement B is FALSE.
- Share of Samsung and Apple in 2012 = [tex]\frac{40612.8+33120.5}{147020.2}[/tex]*100 = 50.15% Hence Statement C is not correct
- Change in Apple market share from 2012 to 2013 is [tex]\frac{38331.8-33120.5}{33120.5}[/tex]*100 = 15.73% ⇒ market share of Apple increases ⇒ statement D is False.
THUS, Statement A is correct.
