Solutions:
1. C) Total number of mobiles sold in January
45000 × 17/100 = 7650.
Sold mobiles in company Bizon in January
7650 × 7/15 = 3570
Sold mobiles in company Bizon in June
7200 × 9/16= 4050
Required ratio = 3570/4050 = 119/135
11. B) In 2007-08 = (99100−88600)/88600×100 = 11.86% increase

In 2008-09 = (99100−97500)/99100×100 = 1.6% increase
In 2009-10 = (104500 − 97500)/97500 = 7.17% increase
In 2010-11 = (116100−104500)/104500 = 11.10% increase
12. C) Profit = Income - Expenditure
Profit in 2006-07 = 88600 - 86000 = ₹ 600 crore
In 2007-08 = 99100 - 87500 = ₹ 11600 cr
In 2008-09 = 975OO - 785OO = ₹ 19000 cr
In 2009-10 = 104500 - 95000 = ₹ 9500 cr
In 2010-11 = 116100 - 105000 = ₹ 11100 cr
Hence the profit of the Railways in 2008-09 is the maximum.
13. C) Average income of the Railways by Passenger trains
= (25800+30500+28800+35500+36100)/5 = 156700/5 = 31340
Hence there are three years in which there is less income than the average income earned by Passenger trains.
14. A) Required percentage = 68600/156700 = 43.77% = 44%
15. C) Required Ratio = 97500/104500 = 195/209 = 195 : 209
