Solutions:
1. (b), total unsold Samsung mobile phones in 2014 and 2015 together = (850000 25%) + (860500 31%) = 212500 + 266755 = 479255
Total unsold Sony mobile phones in 2014 and 2015 together = (650000 44%) + (794000 20%) = 286000 + 158800 = 444800
Number of unsold Samsung phones remains unsold as compared to Sony = 479255-444800 = 34455
2. (d), total mobile phones sold by Micromax = (515000 75% + 480000 88% + 624000 90% +
78600065%+89200075%= 2550225
Average = 2550225/5 = 510045
3. (e), mobile phones sold in 2013 = (480000 88% + 423000 55% + 755000 25% + 715000
80%+74700035%= 1677300
Total unsold mobile phones in 2016 = ( 892000 25% + 842000 40% + 750000 38% + 898000
45%+85000020%= 1418900
Difference = 1677300-1418900 = 258400
4. (c), sales of mobile phones of Sony and Lenovo in 2014 = (56% 650000 + 50% 612000) = 670000
Sales of mobile phones of Sony and Lenovo in 2015 = (80% 794000 + 80% 876000) = 1336000
% increase = (1336000 – 670000)/670000 * 100 = 99.4%
5. (c), Average mobile phones sold in 2012 = (75%575000+72%862000+85%495000+70%600000+70%7850)/5 = 510828
Average mobile phones sold in 2014 = (90%624000+50%612000+56%650000+75%850000+50%812000)/5 = 455020
Therefore difference = 510828 – 455020 = 55808
6. (b), total ball faced by Rohit = (900+1500)/2 = 1200
Total matches played by him = total runs scored/avg. runs scored
Total runs scored = 90*1200/100=1080,
Total matches played= 1080/90=12
