Answers:
Directions (1-5):
1) Answer: a)
√((36 ÷3)×(x ÷3)) = 7.2 ÷ 6 + 0.3
√(4x) = 1.2+0.3
2√x = 1.5
√x = 1.5/2 = 0.75
X = 0.5625
2) Answer: c)
(16*16*10-14) ÷ (32 × 23 × 10-3) = 10x
10-14+3 = 10x
X = -11
3) Answer: b)
2197 ÷ 13 ÷ 2 × 18 + 48 % of 550 + 62 % of 1700 = x
1521 + (48/100)*550 + (62/100)*1700 = x
X = 1521 + 264 + 1054
X = 2839
4) Answer: d)
(1.6)x-3 = (1.6)10 ÷ (4.096)3 × (1.6)7
(1.6)x-3 = (1.6)10 ÷ (1.6)9 × (1.6)7
(1.6)x-3 = 1.610-9+7
(1.6)x-3 = 1.68
x-3 = 8
x = 11
5) Answer: e)
(75/100)* (2/17) * (51/147) * (2/5) * 38465 = x
X = 471
Directions (6-10):
6) Answer: d)
Number of students in college C5
In 2014 = 15/100 * 30000 = 4500
In 2013, 12/100 * 25000 = 3000
Required % Increase = (4500 – 3000)/3000 * 100 = 50%
7) Answer: b)
For 2013:
C1 —- 17 × 250 = 4250
C2 —- 20 × 250 = 5000
C3 —- 21 × 250 = 5250
C4 —- 10 × 250 = 2500
C5 —- 12 × 250 = 3000
C6 —- 15 × 250 = 3750
C7 —- 5 × 250 = 1250
For 2014:
C1 —- 16 * 300 = 4800
C2 —- 22 * 300 = 6600
C3 —- 20 * 300 = 6000
C4 —- 8 * 300 = 2400
C5 —- 15 * 300 = 4500
C6 —- 13 * 300 = 3900
C7 —- 6 * 300 = 1800
Percentage Increase
C1 = (4800 – 4250)/4250 * 100 = 12.94%
C2 = (6600 – 5000)/5000 * 100 = 32 %
C3 = (6000 – 5250)/5250 * 100 = 14.28%
C4 = (2500 – 2400)/2500 * 100 = 4 % Decrease
C5 = (4500 – 3000)/3000 * 100 = 50%
C6 = (3900 – 3750)/3750 * 100 = 4%
C7 = (1800 – 1250)/1250 * 100 = 44 %
Hence, minimum increase is in the college C6
8) Answer: c)
For 2013:
C1 —- 17 × 250 = 4250
C2 —- 20 × 250 = 5000
C3 —- 21 × 250 = 5250
C4 —- 10 × 250 = 2500
C5 —- 12 × 250 = 3000
C6 —- 15 × 250 = 3750
C7 —- 5 × 250 = 1250
For 2014:
C1 —- 16 * 300 = 4800
C2 —- 22 * 300 = 6600
C3 —- 20 * 300 = 6000
C4 —- 8 * 300 = 2400
C5 —- 15 * 300 = 4500
C6 —- 13 * 300 = 3900
C7 —- 6 * 300 = 1800
Percentage Increase
C1 = (4800 – 4250)/4250 * 100 = 12.94%
C2 = (6600 – 5000)/5000 * 100 = 32 %
C3 = (6000 – 5250)/5250 * 100 = 14.28%
C4 = (2500 – 2400)/2500 * 100 = 4 % Decrease
C5 = (4500 – 3000)/3000 * 100 = 50%
C6 = (3900 – 3750)/3750 * 100 = 4%
C7 = (1800 – 1250)/1250 * 100 = 44 %
Hence, decrease is in the college C4.
9) Answer: d)
Required % = [(17 + 20) * 250]/[(16 + 22) * 300] * 100 = 81% approx
10) Answer: a)
Required ratio = 15 × 250: 13 × 300 = 25: 26
