Answers:
Directions (1-5):
1) Answer: b)
?=1/6 of 36 + 1/3 of 123 *2 – 11 [16.67 % = 1/6, 33.33 % = 1/3]
?= 6+41*2-11
?= 6+82-11
?=77
2) Answer: c)
? = (35 – 1) (35 + 1) + 23 *11 – 729 [a2 – b2 = (a + b) (a – b)]
? = 352 – 12 + 23 *11 – 729
? =1225 – 1+ 253 – 729
? =748
3) Answer: d)
? * ? = √384 *√864
? * ? = √ (64x6x144x6)
? * ? =8x6x12 =576
? = 24
4) Answer: b)
 (6 x (136/8) + 132) / (628/16 – 26.25) =?
(102 + 132) / (39.25 – 26.25) = ?
234 / 13 =?
18 = ?
5) Answer: e)
3/7 of 140 + 5/8 of 120 – 1/6 of 36 =?
[42.85 % = 3/7, 62.5 % = 5/8, 16.67 % = 1/6]
? = 60 + 75 – 6 = 129
Directions (6-10):
6) Answer: c)
Total number of female teachers in a city
= > 5000*(28/100)*(75/100) = 1050
Total number of male doctors in a city
= > 5000*(13/100)*(40/100) = 260
Required % = [1050/260]*100 = 404 %
7) Answer: a)
The total number of male engineers in a city
= > 5000*(25/100)*(30/100) = 375
The total number of female lawyers in a city
= > 5000*(23/100)*(48/100) = 552
Required ratio = 375: 552 = 125: 184
8) Answer: d)
The total number of teachers in a city
= > 5000*(28/100) = 1400
The total number of scientist in a city
= > 5000*(11/100) = 550
Required difference = 1400 – 550 = 850
9) Answer: b)
The total number of female engineer, doctor and lawyer in a city
= > [5000*(25/100)*(70/100)] + [5000*(13/100)*(60/100)] + [5000*(23/100)*(48/100)]
= > 875 + 390 + 552 = 1817
10) Answer: c)
Total number of female scientists in a city
= > 5000*(11/100)*(68/100) = 374
Total number of male doctors in a city
= > 5000*(13/100)*(40/100) = 260
Required % = [(374 – 260)/260]*100 = 44 % more
