- 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?56902916145634561146Option 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
- 5 1/8 – 2 1/16 – 1 1/ 16 – 1 1/ 8 = x + 2 1/8.Find the value of x?-11/67-12/89-34/56-66/90-29/16Option 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
- 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 :5667786361Option 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
- 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 ?1013141517Option 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
- 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:110120130140150Option 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
- 13.928 % of 210 + 43.0851 % of 350 + 71.428% of 140 = ?340450280600320Option C
1/7 * 210 + 3/7 * 350 + 5/7 * 140 = ?
30 + 150 + 100 = ?
280 = ?
- 23.002 * ? + 117.002 = 672.123– 232.23170180190200210Option B
23 * ? + 117 = 672 – 232
23 * ? + 117 = 4489 – 232
? * 23 = 4140
? = 180
- (21.23 ÷ 797.90) * (49 ÷ 735) * ? = 1047005700670087009700Option B
(21 ÷ 798) * (49 ÷ 735) * ? = 10
1/38 * 1/15 * ? = 10
? = 5700
- 300.078 = 23.003 × 256.189 ÷ 8.11 – ? – 159.75117456276231876Option C
300 = 23 * (256/8) – x – 160
x = 736 – 160 – 300 = 276
- (4.99/8.92) of 180.181 × 60.12 ÷ 14.93 – ? = 122 167178267278567Option D
(5/9) * 180 * (60/15) – 122 = x
x = 400 – 122 = 278
