1. (1)
7428 x (3/4) x (2/9) x ? = 619
? = ((619 x 4 x 9) / (7428 x 3 x 2)) = 22284 / 44568 = 0.5
2. (1)
? = (560 % 32) x (720 % 48) = 17.5 x 15 = 262.5
3. (3)
748 x ? x 9 = 861696
? = 861696 / (748 x 9) = 128
4. (4)
(3.2/100) of 500 x (2.4/100) of ? = 288
? = (288 x 100 x 100) / (500 x 3.2 x 2.4) = 750
5. (5)
? = 333 x 33 x 3 = 32967
6. (3)
? (5625 / 310) x 91 = 1651.2
= 1646 (approx)
9. (2)
? = (802.86) 2
= 644600 (approx)
8. (4)
? = (1513)2 / 3300
= 2289169/3300 = 693.68 = 695 (approx)
9. (5)
((682/100) of 782) % 850
= ((782 x (700/100)) % 850
= ((782 x (700 / 100)) % 850
= 5474 % 850
= 6.44 = 6.25 (Approx)
10. (2)
(8531 + 6307 + 1093) % (501 + 724 + 396) = 15931 % 1621
= 10 (approx)
11. (4)
45 ( x 1-2) 43 (x 2-3) 83 (x3-4) 245 (x4-5) 975 (x5-6) 4869 (x6-7) 29207
So, 29207 will come in place of ?
12. (1)
289 (+14) 303 (+21) 324 (+28) 352 (+35) 387 (+42) 429 (+49) 478
So, 478 will come in place of ?

16 (x1.5) 24 (x1.5) 36 (x1.5) 54 (x1.5) 81 (x1.5)121.5 (x1.5)182.25
So, 182.25 will come in place of ?
14. (2)
31 (x 1+3) 34 (x2+3) 71 (x3+3) 216 (4+3) 867 (x5+3) 4338 (x6+3) 26031
So, 26031 will come in place of ?
15. (5)
16 (x1) 16 (x2.5) 40 (x3.5) 140 (x6.0) 840 (x9.5) (7980) (x15.5) 123690
1 + 2.5 = 3.5, 2.5 + 3.5 = 6.0
3.5 + 6 = 9.5, 6+9.5 = 15.5
So, 123690 will come in place of ?
16. (4)
Total number of buildings constructed across the state in the year 2006
= 1500 + 1250 + 1480 + 1724 + 1020 + 1136 = 8110
Total number of buildings constructed across the state in the year 2012
= 1700 + 1450 + 1364 + 1896 + 1190 + 1294 = 9164
Required percentage
= (8110/9164) x 100
= 88.4% = 88% (approx)
17. (1)
Total number of buildings constructed in the year 2009
= 1636 + 1335 + 1550 + 1820 + 1115 + 1240 = 8696
Total number of buildings constructed in the year 2011
= 1660 + 1400 + 1600 + 1880 + 1175 + 1280 = 8995
Required difference = 8995 - 8696 = 299
18. (5)
Total number of building constructed across the state over the years
= 8110 + 8354 + 8605 + 8696 + 8710 + 8995 + 9164 = 60634
19. (2)
Total number of buildings constructed in town C in the year 2008 = 1545
Total number of buildings constructed in town C in the year 2007 = 1500
Required percentage increase
= ((1545-1500)/1500) x 100
= (45 x 100) / 1500 = 3%
20. (5)
Total number of buildings constructed in town E over the years = 7765
Total number of buildings constructed in town F over the years = 8610
Required ratio
= 7765 : 8610 = 1553 : 1722
21. (4)
Suppose the age of Ranjana and Rakhi is 15x yrs and 17x years After 6 years the age of Ranjana and Rakhi
= (15x + 6) / (17x + 6) = 9*10
=> 153X + 54 = 150X + 60
=> 3x = 6 => x = 2
So, the age of Ranjana after 6 years = 15 x 2 + 6 = 30+6 = 36 years
22. (21)
R = ((6800 x 100) / (17000 x 4)) = 10%
CI = 17000 [[1 + (10/100)]4- 1]
= 17000 [[11/10]4- 1]
= 17000 [ (11 x 11x 11x 11 - 10 x 10x 10x 10) / (10 x 10 x 10 x 10 )]
= (17000 x 4641) / 10000 = Rs. 7889.7
23. (4)
Total number of sweets
= 80 x (15/100) of 80 + 5 x 80 x (25/100)
= 960 + 100
= 1060
