Question 11 of 20
11. Question
The simple interest accrued on an amount of Rs. 30000 at the end of three years is Rs. 7200. What would be the corresponding compound interest?
Correct
Answer: c)
S.I = PNR/100
7200 = (30000*3*R)/100
R = 720000/90000 = 8 %
Compound interest:
30000*(8/100) = 2400
32400*(8/100) = 2592
34992*(8/100) = 2799.36
C.I = 2400 + 2592 + 2799.36 = Rs. 7791.36
Incorrect
Answer: c)
S.I = PNR/100
7200 = (30000*3*R)/100
R = 720000/90000 = 8 %
Compound interest:
30000*(8/100) = 2400
32400*(8/100) = 2592
34992*(8/100) = 2799.36
C.I = 2400 + 2592 + 2799.36 = Rs. 7791.36
Question 12 of 20
12. Question
The incomes of A and B are in the ratio of 9: 5 and their expenditures are in the ratio of 5: 2. If savings of A and B are Rs. 15000 and Rs. 20000 respectively, then find the income of B?
Correct
Answer: a)
The incomes of A and B are in the ratio of = 9: 5 (9x, 5x)
The expenditure of A and B are in the ratio of = 5: 2
Income = Expenditure + Savings
According to the question,
= > (9x – 15000)/(5x – 20000) = (5/2)
= > 18x – 30000 = 25x – 100000
= > 70000 = 7x
= > x = 10000
The income of B = 5x = Rs. 50000
Incorrect
Answer: a)
The incomes of A and B are in the ratio of = 9: 5 (9x, 5x)
The expenditure of A and B are in the ratio of = 5: 2
Income = Expenditure + Savings
According to the question,
= > (9x – 15000)/(5x – 20000) = (5/2)
= > 18x – 30000 = 25x – 100000
= > 70000 = 7x
= > x = 10000
The income of B = 5x = Rs. 50000
Question 13 of 20
13. Question
A can finish a work in 20 days. B can finish the same work in 12 days and that of C in 15 days. B and C start the work but they are forced to leave after 4 days. How many days A will take to finish the remaining work?
Correct
Answer: d)
(B + C)’s one day work = (1/12) + (1/15) = 27/(12*15) = 3/20
(B + C)’s four days work = (3/20)*4 = 3/5
Remaining work = 1 – (3/5) = 2/5
Remaining work done by A in,
= > (2/5)*20 = 8 days
Incorrect
Answer: d)
(B + C)’s one day work = (1/12) + (1/15) = 27/(12*15) = 3/20
(B + C)’s four days work = (3/20)*4 = 3/5
Remaining work = 1 – (3/5) = 2/5
Remaining work done by A in,
= > (2/5)*20 = 8 days
Question 14 of 20
14. Question
The diameter and length of the cone is 42 cm and 15 cm. Find the ratio between the curved surface area to that of total surface area of the cone?
Correct
Answer: c)
The curved surface area of a cone = πrl = (22/7)*21*15
The total surface area of a cone = πrl + πr^{2} = (22/7)*21*[15 + 21]
Required ratio = {(22/7)*21*15}: {(22/7)*21*[15 + 21]}
= > 15: 36 = 5: 12
Incorrect
Answer: c)
The curved surface area of a cone = πrl = (22/7)*21*15
The total surface area of a cone = πrl + πr^{2} = (22/7)*21*[15 + 21]
Required ratio = {(22/7)*21*15}: {(22/7)*21*[15 + 21]}
= > 15: 36 = 5: 12
Question 15 of 20
15. Question
Karuna and Mahesh started a business by investing in the ratio of 5: 4. 20 % of total profit goes to charity and the remaining amount will be shared by both of them. If the share of Karuna is Rs. 25000, then find the total profit at the end of the year?
Correct
Answer: b)
The share of Karuna = Rs. 25000
5’s = 25000
1’s = 5000
Total share of Karuna and Mahesh = 9’s = Rs. 45000
(80/100)*Total profit = 45000
Total profit = 45000*(100/80) = Rs. 56250
Incorrect
Answer: b)
The share of Karuna = Rs. 25000
5’s = 25000
1’s = 5000
Total share of Karuna and Mahesh = 9’s = Rs. 45000
(80/100)*Total profit = 45000
Total profit = 45000*(100/80) = Rs. 56250

Direction (1-5)
1) Answer: d)
(83/500)*17200 + (219/700)*2170 + (137/300)*19680 = x
X = 2855.2 + 678.9 + 8987.2
X = 12521.3
2) Answer: a)
(48/100)*5250 + (96*96*3)/8 + 125 = 5x
5x = 2520 + 3456 + 125
5x = 6101
X = 1220.2
3) Answer: c)
(79/15)*4350 + (120/19)*3857 = x + 640
22910 + 24360 – 640 = x
X = 46630
4) Answer: b)
(27604/67) + (5115/31) + (4312/11) + (3094/14) = x
X = 412 + 165 + 392 + 221
X = 1190
5) Answer: d)
(3/7) * (35/13) * 3055 – x + (56/100)*7550 = 63
3525 – x + 4228 = 63
X = 3525 + 4228 – 63
X = 7690
Direction (6-10)
6) Answer: e)
I. (x^{12/7} ÷ 16) = (49 ÷ x^{2/7})
X^{12/7} × x^{2/7 }= 49 × 16
X^{14/7} = 49 × 16
X^{2} = 49 × 16
X = + (7*4), – (7*4) = +28, -28
II. y^{31/7} × y^{4/7} × 9 = 324 × y^{3}
Y^{31/7 + 4/7 –3} = 324/9
Y^{2} = 36
Y = 6, -6
Can’t be determined
7) Answer: a)
I. 15x^{2} – 40x + 16 = 10x^{2} – 22x
5x^{2} – 18x + 16 = 0
5x^{2} -10x – 8x + 16 = 0
5x(x – 2) -8(x – 2) = 0
(5x – 8) (x – 2) = 0
X = 8/5, 2 = 1.6, 2
II. 17y^{2} +22y + 9 = 13y^{2} + 10y
4y^{2} + 12y + 9 = 0
4y^{2} + 6y + 6y + 9 = 0
2y (2y + 3) + 3(2y + 3) = 0
(2y + 3) (2y + 3) = 0
Y = -3/2, -3/2 = -1.5, -1.5
X > y
8) Answer: e)
I. 7x^{2} + 37x + 36 = 0
7x^{2} + 28x + 9x + 36 = 0
7x (x + 4) +9(x + 4) = 0
(7x + 9)(x + 4) = 0
X = -9/7, -4 = -1.28, -4
II. 9y^{2} + 35y + 24 = 0
9y^{2} + 27y + 8y + 24 = 0
9y(y + 3) + 8(y + 3) = 0
(9y + 8) (y + 3) = 0
Y = -8/9, -3 = -0.89, -3
Can’t be determined
9) Answer: c)
5x – 4y = -12 —> (1)
3x + 5y = -59 —> (2)
By solving the equation (1) and (2), we get,
X = -8, y = -7
X < y
10) Answer: a)
I. 15x^{2} + 68x + 77 = 0
15x^{2} + 35x + 33x + 77 = 0
5x (3x + 7) +11 (3x + 7) = 0
(5x + 11) (3x + 7) = 0
X = -11/5, -7/3 = -2.2, -2.33
II. 3y^{2} + 29y + 68 = 0
3y^{2} + 12y + 17y + 68 = 0
3y(y + 4) + 17(y + 4) = 0
(3y + 17) (y +4) = 0
Y = -17/3, -4 = – 5.67, -4
X > y
11) Answer: c)
S.I = PNR/100
7200 = (30000*3*R)/100
R = 720000/90000 = 8 %
Compound interest:
30000*(8/100) = 2400
32400*(8/100) = 2592
34992*(8/100) = 2799.36
C.I = 2400 + 2592 + 2799.36 = Rs. 7791.36
12) Answer: a)
The incomes of A and B are in the ratio of = 9: 5 (9x, 5x)
The expenditure of A and B are in the ratio of = 5: 2
Income = Expenditure + Savings
According to the question,
= > (9x – 15000)/(5x – 20000) = (5/2)
= > 18x – 30000 = 25x – 100000
= > 70000 = 7x
= > x = 10000
The income of B = 5x = Rs. 50000
13) Answer: d)
(B + C)’s one day work = (1/12) + (1/15) = 27/(12*15) = 3/20
(B + C)’s four days work = (3/20)*4 = 3/5
Remaining work = 1 – (3/5) = 2/5
Remaining work done by A in,
= > (2/5)*20 = 8 days
14) Answer: c)
The curved surface area of a cone = πrl = (22/7)*21*15
The total surface area of a cone = πrl + πr^{2} = (22/7)*21*[15 + 21]
Required ratio = {(22/7)*21*15}: {(22/7)*21*[15 + 21]}
= > 15: 36 = 5: 12
15) Answer: b)
The share of Karuna = Rs. 25000
5’s = 25000
1’s = 5000
Total share of Karuna and Mahesh = 9’s = Rs. 45000
(80/100)*Total profit = 45000
Total profit = 45000*(100/80) = Rs. 56250

16) Answer: c)
The total employees in organization P of all the given department
= > 1250 + 1130 + 850 + 740 + 520 = 4490
The total employees in organization R of all the given department
= > 960 + 1380 + 780 + 1020 + 360 = 4500
Required difference = 4500 – 4490 = 10
17) Answer: a)
The total number of employees working in Accounts department
= > 1130 + 1560 + 1380 + 1050 + 980 = 6100
The total number of employees working in IT department

Required ratio = 6100: 2090 = 610: 209
18) Answer: d)
The total number of male to that of female of production department in organization Q = 4: 5
The total number of male to that of female in production department in organization S = 3: 2
The total males of production department in organization Q and S together
= > 1170*(4/9) + 890*(3/5)
= > 520 + 534 = 1054
The total females of production department in organization Q and S together
= > 1170*(5/9) + 890*(2/5)
= > 650 + 356 = 1006
Required difference = 1054 – 1006 = 48
