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
In
200809 = (99100−97500)/99100×100 = 1.6% increase
In
200910 = (104500 − 97500)/97500 = 7.17% increase
In
201011 = (116100−104500)/104500 = 11.10% increase
12. C) Profit =
Income  Expenditure
Profit
in 200607 = 88600  86000 = ₹ 600 crore
In
200708 = 99100  87500 = ₹ 11600 cr
In
200809 = 975OO  785OO = ₹ 19000 cr
In
200910 = 104500  95000 = ₹ 9500 cr
In
201011 = 116100  105000 = ₹ 11100 cr
Hence
the profit of the Railways in 200809 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
