Directions (6 – 10) Study the following information carefully and answer the given questions:
Following table shows the percentage distribution of expenses of four departments in 4 different years.

In the year 2012 = 60 lakhs
In the year 2013 = 68 lakhs
In the year 2014 = 72 lakhs

10) Find the ratio between the total expenses of marketing and agriculture department in the year 2012 to that of total expenses of agriculture department in the year 2014?
Answers:
1). Answer: a)
Compound Interest = Rs. 9270
Total amount = 75000 + 9270 = Rs. 84270
Number of years (n) = 2
Total amount = P*(1 + (r/100))n
84270 = 75000*(1 + (r/100))2
(84270/75000) = [(100 + r)/100]2
(2809/2500) = [(100 + r)/100]2
(53/50)2 = [(100 + r)/100]2
(53/50) = [(100 + r)/100]
106 = 100 + r
r = 6 %
2). Answer: d)
Total amount = Rs. 73205
Ratio of the sum invested by P and R = 3: 2 (3x, 2x)
3x = 75000
X = 25000
Principle amount invested by R = 2x = Rs. 50000
Total amount = P*(1 + (r/100))n
73205 = 50000*[110/100]n
73205/50000 = [11/10]n
14641/10000 = [11/10]n
(11/10)4 = [11/10]n
n = 4
Number of years = 4 years
3). Answer: b)
Total amount = Rs. 92238.30
Total amount = P*(1 + (r/100))n
92238.30 = P*(1 + (10/100))4
92238.30 = P*(110/100)4
92238.30 = P*(11/10)4
P = 92238.30*(10000/14641)
P = Rs. 63000
4). Answer: c)
The ratio of the sum invested by P and S = 5: 6 (5x, 6x)
5x = 75000
X = 15000
The principle amount invested by S = 6x = Rs. 90000
Total amount = Rs. 104976
Total amount = P*(1 + (r/100))n
104976 = 90000*[(100 + r)/100]2
(104976/90000) = [(100 + r)/100]2
(729/625) = [(100 + r)/100]2
(27/25)2 = [(100 + r)/100]2
27/25 = [(100 + r)/100]
108 = 100 + r
r = 8 %
Rate of interest = 8 %
5). Answer: c)
Principle amount invested by Q = (80/100)*75000
= > Rs. 60000
Compound interest = Rs. 9457.50
Total amount = 60000 + 9457.50 = Rs. 69457.50
Total amount = P*(1 + (r/100))n
69457.50 = 60000*(1 + (5/100))n
(69457.50/60000) = (105/100)n
(694575/600000) = (21/20)n
9261/8000 = (21/20)n
(21/20)3 = (21/20)n
n = 3
Number of years = 3 years
Direction (6-10)
6). Answer: b)
Total expenses of 4 departments in the year 2012 = 60 lakhs
Total expenses of finance department in the year 2012
= > 60*(20/100) = 12 lakhs
Profit % = 20 %
Total income of finance department in the year 2012
= > Income = 12*(120/100)
= > Income = 14.4 lakhs
7). Answer: d)
The total profit earned by marketing department in the year 2013
Expense of marketing in the year 2013 = 68*(25/100) = 17 lakhs
Income of marketing in the year 2013 = 17*(115/100) = 19.55 lakhs
Profit = 2.55 lakhs
Total expenses of R & D department in the year 2014 and 2015 together
= > 72*(26/100) + 75*(20/100)
= > 18.72 + 15 = 33.72 lakhs
Required difference = 33.72 – 2.55 = 31.17 lakhs = 3117000
8). Answer: a)
The total expenses of agriculture in all the given years together
= > 60*(28/100) + 68*(30/100) + 72*(18/100) + 75*(30/100)
= > 16.8 + 20.4 + 12.96 + 22.5
= > 72.66 lakhs
Required average = 72.66/4 = 18.165 lakhs = 1816500
9). Answer: c)
The profit earned by marketing department the year 2014 = 4.5 lakhs
Expense of marketing department the year 2014 = 72*(25/100) = 18 lakhs
Profit % of marketing department the year 2014 = (4.5/18)*100 = 25 %
The profit earned by R & D department the year 2015 = 3 lakhs
Expense of R & D department the year 2015 = 75*(20/100) = 15 lakhs
Profit % of R & D department the year 2015 = (3/15)*100 = 20 %
Required % = (25/20)*100 = 125 %
10). Answer: a)
The total expenses of marketing and agriculture department in the year 2012
= > 60*(50/100) = 30 lakhs
The total expenses of agriculture department in the year 2014
= > 72*(18/100) = 12.96 lakhs
Required ratio = 30: 12.96 = 3000: 1296 = 125: 54
