Answers :
1) Answer: d)
The ratio of investment = 7 : 12 : 22
The ratio of profit = 7 : 15 : 11
Ratio of investment * Ratio of Period of investment = Ratio of Profit
Ratio of Period of investment = Ratio of Profit/ Ratio of investment
According to the question,
= > (7/7) : (15/12) : (11/22)
= > 1 : (5/4) : (1/2)
= > 4 : 5 : 2
2) Answer: a)
(1/8) + (1/6) + 1 boy = (1/3)
1 boy = (1/3) – [(1/8) + (1/6)]
1 boy = (1/3) – (7/24) = (8 – 7)/24 = 1/24
The share of two men and a boy = (1/8) : (1/6) : (1/24)
= > 3 : 4 : 1
8’s = 5200
1’s = 650
The share of boy = Rs. 650
3) Answer: c)
C.P1 = 12000, Loss % = 6 %
S.P1 = 12000 * (94/100) = Rs. 11280
With that money she purchased another dining table and sold it at the profit of 15 %,
C.P2 = 11280, Profit % = 15 %
S.P2 = 11280*(115/100) = Rs. 12972
The overall profit = 12972 – 12000 = Rs. 972
4) Answer: a)
Amount = P*(1 + r/100)n
56687.04 = 45000*(1 + (8/100))n
56687.04 /45000 = (108/100)n
5668704 /4500000 = (27/25)n
(27/25)3 = (27/25)n
n = 3 years
5) Answer: d)
Work = Men*days
16 m * 24 = 20 w * 36
8 m = 15 w
12 m + 15 w = 12*(15/8) w + 15 w = (45/2) w + 15 w = 75/2 w
Women     days
20Â Â Â Â Â Â Â Â Â Â Â Â Â Â 36
(75/2)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ?
(20*36) = (75/2)*x
X = (20*36*2)/75 = 96/5 = 19 1/5 days

6) Answer: a)
The total number of male employees in company P, R and T together
= > 900 + 1200 + 1150 = 3250
The total number of female employees in company Q, S and U together
= > 1050 + 1100 + 950 = 3100
Required ratio = 3250 : 3100 = 65 : 62
7) Answer: d)
The ratio of officers and clerks in company R = 3 : 4
The ratio of officers and clerks in company T = 2 : 3
The total number of officers in company R and T together
= > 2100*(3/7) + 2000*(2/5)
= > 900 + 800 = 1700
The total number of clerks in company R and T together
= > 2100*(4/7) + 2000*(3/5)
= > 1200 + 1200 = 2400
Required difference = 2400 – 1700 = 700
8) Answer: b)
Total number of employees in company P and Q together
= > 1650 + 2000 = 3650
Total number of employees in company T and U together
= > 2000 + 2000 = 4000
Required % = (3650/4000)*100 = 91.25 %
9) Answer: a)
The total number of male employees in all the given companies together
= > 900 + 950 + 1200 + 1350 + 1150 + 1050
= > 6600
Required average = 6600/6 = 1100
10) Answer: c)
Total number of female employees in company Q and R together
= > 1050 + 900 = 1950
Total number of female employee in company U
= > 950
Required % = [(1950 – 950)/950]*100 = 105 %
