Quantitative Aptitude

Number of shares bought by new investors in


2004=9900-5940=3960 22. Answer: A
Number of shares bought by new investors in Pipe B fill the tank = 30 * 2/3 = 20 hours
2002=9000*7/(8+7)=4200 A + B + C = 1/10 + 1/20 – 1/30
Required sum=3960+4200=8160 = 6 + 3 – 2/60
= 7/60
19. Answer: D Required Volume = 7/60 * 38808 = 4527.6
The market value in
2003=13500*180=Rs.2430000 23. Answer: B
The liability value in C alone empty the tank x = 36 * 2/3 = 24 hours
2003=2430000*1/5=Rs.486000 A + B + C = 1/36 + 1/12 – 1/24 = 2 + 6 – 3/72
The other expenses in 2003=486000- = 5/72
12000=Rs.474000 5/72 * Volume of tank = 428
The gross value in 2003=2430000- 5/72 * 22/7 * r2 * 10 = 428
(486000+474000)=Rs.1470000 r2 = 196
The gross value in r = 14
2002=1470000*40/100=Rs.588000
The market value in 2002=9000*75=Rs.675000 24. Answer: C
The sum of the liability and other expense in Pipe B fill the tank = 3.5 * 100/25 = 14 hours
2002=675000-588000=Rs.87000 Pipe C fill the tank = 14 * 5/2 = 35 hours
A + 1/14 – 1/35 = 3575/19250
20. Answer: A 70A + 5 – 2/70 = 13/70
The cost price per share in 2007=90*5/3=Rs.150 70A = 10
The cost price per share in 2005=75+65=Rs.140 A = 1/7
Required difference=10500*150- A alone fill 40% of the tank = 7 * 40/100 = 2.8
7000*140=Rs.595000 hours

21. Answer: C 25. Answer: A


The average number of shares bought in 2002 22/7 * r * r * 28 = 38808
and 2003=(9000+13500)/2=11250 Radius of the tank W = 21
Required percentage=(11250- Radius of M = 120/100 * 21 = 25.2
7500)/7500*100=3750/75=50% more Height of M = 120/100 * 35 = 42

TSA of M = 2 * 22/7 * 25.2 * (42 + 25.2) = Time ratio of A and B = 6:5


10644.48 If B is 60% more efficient than A, then
TSA of W = 2 * 22/7 * 21 * (28 + 21) = 6468 Time ratio of A and B = 6x:6x * 100/160
Required sum = 6468 + 10644.48 = 17112.48 = 6x:15x/4
6x – 15x/4 = 18
26. Answer: B 9x/4 = 18
22/7 * r * r * 28 = 38808 x=8
Radius of the tank W = 21 A and B complete the work in 12 days = 12/(6 *
22/7 * r1*r1 * 35 = 5390 8) + 12/(5 * 8)
Radius of tank Y = 7 = 11/20
Required ratio = (2 * 22/7 * 21 * 28):(2 * 22/7 * 7 Remaining work = 1 – 11/20 = 9/20
* (35 + 7))
= 2:1 31. Answer: C
Investment of A and B together and C and D
27. Answer: A together = 75:100 = 3:4
Profit ratio of Avni and Beena = 10:27 Profit share of A and B = 3/7 * 10500 = 4500
P * x/(1.2P * x + (1.2P * 125/100 * (12-x)) = Profit share of A = 4500 * 2/3 = 3000
10/27
Px/P(1.2x + 18 – 1.5x) = 10/27 32. Answer: C
27x = 180 – 3x From statement I,
x=6 3x * 6 + 24 = N
18x + 24 = N
28. Answer: C So, statement I alone is not sufficient to answer
Required difference = (51 – 20)/(20 + 51) * the question.
14200 From statement II,
= 6200 3x * 1/3 * y = N
N/x= Completely divisible
29. Answer: E So, statement II alone is not sufficient to answer
Since we can’t able to find the value of P the question.
From statement III,
30. Answer: B 30<Number of students <40 and 200 < number
Efficiency of A and B = 100:120 = 5:6 of chocolates < 300.

So, statement III alone is not sufficient to answer From statement I,


the question. Investment of A, B and C is not given
From I, II and III, So, Statement I alone is not sufficient to answer
3x * 6 + 24 = N the question.
18x + 24 = N From statement II,
30<3x<40 Investment of A and B together = 2x
180<18x<240 Investment of C = 2x/2 = x
Possible values of x = 11,12, 13 So, Statement II alone is not sufficient to answer
3x * 1/3 * y = N the question.
y = N/x From statement III,
N/x is completely divisible Ratio of the profit share of C and A and B
So the possible value of x is 12 Together = 3:8
N = 18 * 12 + 24 = 240 So, Statement III alone is not sufficient to
So ALL I, II and III together required to answer answer the question.
