1. An admission of a school has increased in every academic year by 6%. If the number of students in the previous academic year is 2500, then what is the number of students in the next year?
   5690
   2916
   1456
   3456
   1146
   Option B
   8% of 2500 = 8/100 x2500 = 200
   Total no., of students in the current year = 2500 + 200 = 2700
   8% of 2700= 216
   So number of students in the next year = 2700 + 216 = 2916
   
   
    



2. 5 1/8 – 2 1/16 – 1 1/ 16 – 1 1/ 8 = x + 2 1/8.Find the value of x?
   -11/67
   -12/89
   -34/56
   -66/90
   -29/16
   Option E
   Take 1/8 as common ,
   Then 1/8 ( 5 – 2/2 – ½ -1) = x + 2 1/8
   1/8 ( 5 -1 -1/2 -1) = x + 2 1/8
   1/8 ( 5-2-1/2) = x + 17 /8
   1/8 ( 5 /2) = x + 17 /8
   5/16 = x + 17/8
    X = - 29/16
   
   
    



3. A shoots the balloons 6 times to B is 4 but A blasts only once in 2 shots while B blasts once in 3 shots. When B has missed 28 times, A has blasted :
   56
   67
   78
   63
   61
   Option D
   Let the no of shots be x. Then,
   Shots fired by A =(6/10)x
   Shots fired by B = (4/10)x
   blasting shots by A = 1/2 of (6/10)x = (6/20)x
   Shots missed by B = 1/3 of (4/10)x = (4/30)x
   (4/30)x = 28 ⇒ x = 210
   Balloons blasts by A = (6/20)x = 6 / 20 x 210 =63
   
   
    



4. In a group of lions and rabbits, the number of legs are 30 more than twice the number of heads. What is the number of lions in the group ?
   10
   13
   14
   15
   17
   Option D
   Let the number of lions be x and number of rabbits be y.
   Then 4x + 2y = 2(x + y) + 30
   => 2 x = 30
   => x = 15
   
   
   
   
   
    



5. A tank is 3/5 full. If 28 litres of water is added to the tank, it becomes 5/6 full. The capacity of the tank is:
   110
   120
   130
   140
   150
   Option B
   Let the capacity of the tank be x litres.
   Then, (5x/6 - 3x/5) = 28
   => 25x - 18x / 30
   = > 7x / 30 = 28
   => 7x = 840
   => x = 120
   
   
    



6. 13.928 % of 210 + 43.0851 % of 350 + 71.428% of 140 = ?
   
   
   340
   450
   280
   600
   320
   Option C
   1/7 * 210 + 3/7 * 350 + 5/7 * 140 = ?
   
   30 + 150 + 100 = ?
   
   280 = ?
   
   
   
    



7. 23.002 * ? + 117.002 = 672.123– 232.23
   
   
   170
   180
   190
   200
   210
   Option B
   23 * ? + 117 = 672 – 232
   
   23 * ? + 117 = 4489 – 232
   
   ? * 23 = 4140
   
   ? = 180
   
   
   
    



8. (21.23 ÷ 797.90) * (49 ÷ 735) * ? = 10
   
   
   4700
   5700

   Option B
   (21 ÷ 798) * (49 ÷ 735) * ? = 10
   
   1/38 * 1/15 * ? = 10
   
   ? = 5700
   
   
   
    



9. 300.078 = 23.003 × 256.189 ÷ 8.11 – ? – 159.75
   
   
   117
   456
   276
   231

   Option C
   
   300 = 23 * (256/8) – x – 160
   
   x = 736 – 160 – 300 = 276
   
   
   
   
    



10. (4.99/8.92) of 180.181 × 60.12 ÷ 14.93 – ? = 122
