Answers:
Directions (1-5):
1) Answer: c)
26 % of 350 – 32 % of 600 = x – 158 – 272
(26/100)*350 – (32/100)*600 = x – 158 – 729
91 – 192 + 158 + 729 = x
X = 786
2) Answer: d)
6 of 300 + 3 of 430 = x% of 750
(300*6) + (3*430) = (x/100)*750
1800 + 1290 = 15x/2
(3090*2)/15 = x
X = 412
3) Answer: a)
 (554 + 959 – 433)/15 = x
X = 1080/15 = 72
4) Answer: c)
 [((150 ÷ 3) ÷ 10)2 + (64 × 9)1/2] = x2
(150/30)2 + (8*3) = x2
25 + 24 = x2
X2 = 49
X = 7
5) Answer: b)
x ÷ 4 + 72 × 15 = 4824 + 1598
(x/4) + 1080 = 6422
(x/4) = 5342
X = 5342*4 = 21368
Directions (6-10):
6) Answer: e)
Total number of tyres rejected by the company P
= > 3200000*(2/100) = 64000
Total number of tyres rejected by the company T
= > 4000000*(1.5/100) = 60000
Required % = [(64000 – 60000)/60000]*100 = 7 % more
7) Answer: a)
The average number of tyres manufactured by all the given companies together
= > (32 + 26 + 48 + 16 + 40)/5
= > 162/5 = 32.4 lakhs
8) Answer: c)
The total number of tyres sold by the company Q
= >2600000*(95/100)*(84/100) = 2074800
The total number of tyres sold by the company S
= > 1600000*(97/100)*(80/100) = 1241600
Required difference = 2074800 – 1241600 = 833200
9) Answer: d)
The total number of tyres rejected by the company Q
= > 26*(5/100) = 1.3 lakhs
The total number of tyres rejected by the company R
= > 48*(4/100) = 1.92 lakhs
Required ratio = 1.3: 1.92 = 130: 192 = 65: 96
10) Answer: b)
Total number of tyres sold by the company P
= > 3200000*(98/100)*(78/100) = 2446080
Total number of tyres sold by the company R
= > 4800000*(96/100)*(72/100) = 3317760
Required % = (2446080/3317760)*100 = 73.726 = 75 %
