Option E
(19.99)^2 + 24.98% of 127.98 = ?^2 *75.01%
=>(20)^2 + 25% of 128 = ?^2 * 75%
=>?^2 * (3/4) = 400+32
=>?^2 = 432 *(4/3)
=>? = (576)^1/2
=> ? = 24

Option B
(500.01% of 24.89) /24.98 = (?)^1/2 – (63.98)^1/2
=>(500% of 25)/25 = (?)^1/2 – (64)^1/2
=>(?)^1/2 – 8 = 125/25
=>(?)^1/2 = 8+5
=>? = 169

6. Directions(6-10):Answer the questions based on the information given below.

The graph represents the percentage of female population out of the total population of five different villages in 2010 and 2011. 7. Male population of Sholapur was increased by 20% from 2011 to 2012 and male population of Sholapur in 2012 was 3300.

5214
5775
6565
4850
5200
Option B
Male population of Sholapur in 2011 = 3300/1.2
= 2750
Female population of Sholapur in 2011 = (2750/0.55)*0.45 = 2250
Female population of Sholapur in 2012 = 2250*1.1 = 2475
Total population of Sholapur in 2012 = 2475 + 3300 = 5775

2255
2394
2002
2212
Option C
Total population of Gwalior in 2010 = 2415/0.46
= 5250

Option D
Female population of Varanasi in 2010 = 0.34*2800
= 952
Female population of Varanasi in 2011 = (1920/0.6)*0.4 = 1280
