Answers :
Directions (1-5) :
1) Answer: B
(3.99)2÷ 7.99 x 48.01% of 4500 – (? x 3.99) = √4096.032
=> 42÷ 8 x 48/100 x 4500 – (? x 4) = √4096
=> 16 ÷ 8 x 2160 – (? x 4) = 64
=> 4320 – (? X 4) = 64
=> 4320 – 64 = (? x 4)
=> ? = 4256/4
=> ? = 1064
2) Answer: E
(444.212 ÷ 36.99 x 4.012) x 23.987 = ? x 5.87
=> (444 ÷ 37 x 4) x 24 = ? x 6
=> (12 x 4) x 24 = ? x 6
=> 48 x 24 = ? x 6
=> ? = 48 x 24/6
=> ? = 192
3) Answer: C
√15375.99 ÷√961.101 x √1023.898 = ? x 8.013
=> √15376 ÷ √961 x √1024 = ? x 8
=> 124 ÷ 31 x 32 = ? x 8
=> 4 x 32 = ? x 8
=> ? = 4 x 32/8
=> ? = 16
4) Answer: D
459.909 ÷ 23 x 5.898 – 35 x 2.999 + 1155.978 ÷ 17 = ?
=> 460 ÷ 23 x 6 – 35 x 3 + 1156 ÷ 17 = ?
=> 20 x 6 – 105 + 68 = ?
=> 120 – 105 + 68 = ?
=> 188 – 105 = ?
=>83 = ?
5) Answer: E
(9.8)2 ÷ (5.001)2 x 44.99% of 1200 + 788.999 ÷ 263 = ?
=> (10)2 ÷ (5)2 x 45/100 x 1200 + 789 ÷ 263 = ?
=> 100 ÷ 25 x 540 + 3 = ?
=> 4 x 540 + 3 = ?
=> 2160 + 3 = ?
=> 2163 = ?
Directions (6-10):
6) Answer: B
Quantity of wine in the initial mixture = 11/19 x 133 = 77 litres
Quantity of water in the initial mixture = 8/19 x 133 = 56 litres
Quantity of wine in the final mixture = 77 – 11/19 x 76 + 7
= 77 – 44 + 7
= 40 litres
Quantity of water in the final mixture = 56 – 8/19 x 76 + 6
= 56 – 32 + 6
= 30 litres
Required difference = 40 – 30 = 10 litres
7) Answer: D
Ratio of shares in the profit:
Deepak : Kailash : Harit : Manish = (35000 + 40000 x 2) : (25000 + 35000 x 2) : (40000 x 2 + 30000) : (50000 x 2 + 30000)
= 115000 : 95000 : 110000 : 130000
= 23 : 19 : 22 : 26
Required difference = (26 – 23)/(23 + 19 + 22 + 26) x 180000
= 3/90 x 180000
= Rs.6000
8) Answer: D
We know that
Amount on CI = P x (1 + r/100)t
Let, amount invested in the account of Vikash = Rs.m
And amount invested in the account of Kavita = Rs.n
m x (1 + 25/100)30Â = n x (1 + 25/100)33
=> m x (1 + ¼)30 = n x (1 + ¼)33
=> m x (5/4)30Â = n x (5/4)33
=> m/n = (5/4)33 – 30
=> m/n = (5/4)3
=> m/n = 125/64
Amount invested by him in the account of Vikash = 125/(125 + 64) x 75600
= 125/189 x 75600
= Rs.50000
9) Answer: C
Probability of getting a yellow ball = 1 – 0.15 – 0.25 – 0.3 = 0.3
Required probability = 0.15 + 0.25 + 0.3 = 0.7 = 7/10
10) Answer: D
12c(k + 3)x 8c3 x 6c2 = 665280
=>12c(k + 3)x 56 x 15 = 665280
=>12c(k + 3)= 665280/840
=>12c(k + 3)Â = 792
=>12c(k + 3)Â =Â 12c5
=> k + 3 = 5
=> k = 5 – 3
=> k = 2
