ANSWERS
Solutions (1-5)
1. (1)
From the table, we can say that since the sum is maximum for Bihar, the average is also maximum for Bihar.
2. (4)
Percentage of qualified candidates from Gujarat over those appeared from Gujarat in 2007 = 340/4100 * 100 = 8.3%
Percentage of qualified candidates from Gujarat over those appeared from Gujarat in 2008 = 300/3400 * 100 = 8.8%
Percentage of qualified candidates from Gujarat over those appeared from Gujarat in 2009 = 260/3250 * 100 = 8%
Percentage of qualified candidates from Gujarat over those appeared from Gujarat in 2010 = 360/3900 * 100 = 9.2%
Percentage of qualified candidates from Gujarat over those appeared from Gujarat in 2007 = 240/2850 * 100 = 8.4%
3. (2)
Required average = 1420/5 = 284
4. (4)
Required percentage = 172/192 * 100 = 89.5%
5. (1)
Required ratio = 16700 : 17500 = 167 : 175
Solutions (6-10)
6. (2)
Required number of days to make one chair = (2 * 4)/(2 + 4) = 4/3
Required number of days to make 3 chairs = 4
7. (4)
Required number of days = 3 + 2 + 12 + 15 = 32
8. (3) LCM of 2, 3, 6 = 6
Required number of days = 6/ (6/2 + 6/3 + 6/6) = 1
9. (1)
Required number of days = (10 * 15)/ (10 + 15) = 6
10. (4)
