Directions (1 – 5): In the following questions, two equations I and II are given. You have to solve both the equations and give Answer as,
a) If x > y
b) If x ≥ y
c) If x < y
d) If x ≤ y
e) If x = y or the relation cannot be established
3x + 4y = 31
x + 3y = 17
Correct
Answer: a)
3x + 4y = 31–> (1)
x + 3y = 17 —> (2)
By solving the equation (1) and (2), we get,
X = 5, y = 4
X > y
Incorrect
Answer: a)
3x + 4y = 31–> (1)

Question 7 of 20
7. Question
Directions (6 – 10): What value should come in place of question mark (?) in the following questions?
√2916 ÷ 9 = 12^{3} + 27 % of 1500 – ?
Correct

Question 8 of 20
8. Question
Directions (6 – 10): What value should come in place of question mark (?) in the following questions?
(2/11) of 825 – 14 – (? * √2916)= 28
Correct
Answer: d)
(2/11)*825 – 14 – (x*54) = 28
150 – 14 – (x*54) = 28
150 – 14 – 28 = (x*54)
108 = (x*54)
X = 2
Incorrect
Answer: d)
(2/11)*825 – 14 – (x*54) = 28
150 – 14 – (x*54) = 28

X = 2
Question 9 of 20
9. Question
Directions (6 – 10): What value should come in place of question mark (?) in the following questions?
[(324 ÷ 9)^{1/2} + (728 ÷ 13)^{2}] = ?^{2} – 702
Correct
Answer: a)
(324/9)^{1/2} + (728/13)^{2} = x^{2} – 702
36^{1/2} + 56^{2} = x^{2} – 702
6 + 3136 + 702 = x^{2}
X^{2} = 3844
X = 62
Incorrect
Answer: a)
(324/9)^{1/2} + (728/13)^{2} = x^{2} – 702
36^{1/2} + 56^{2} = x^{2} – 702
6 + 3136 + 702 = x^{2}
X^{2} = 3844
X = 62
Question 10 of 20
10. Question
Directions (6 – 10): What value should come in place of question mark (?) in the following questions?
855 ÷ 57 % of 500 =? – 165
Correct
Answer: c)
855 ÷ 57 % of 500 = x – 165
855/ [(57/100)*500] = x – 165
(855/285) = x – 165
3 + 165 = x
X = 168
Incorrect
Answer: c)
855 ÷ 57 % of 500 = x – 165
855/ [(57/100)*500] = x – 165
(855/285) = x – 165
3 + 165 = x
X = 168
Question 11 of 20
11. Question
P, Q and R started a business by investing in the ratio of 4: 5: 7. After 4 months, P invested Rs. 5000 and R withdraw Rs. 3000. At the end of the year, the share’s are in the ratio of 65: 75: 102. Then find the initial investment of Q?
Rajesh takes a loan of Rs. 20000 and pays back Rs. 23328 after 2 years at some rate of interest compounded annually. Find the rate of interest?
Correct
Answer: c)
Amount = P*(1+(r/100))^{n}
23328 = 20000*(1+(r/100))^{2}
((100+r)/100)^{2} = 23328 /20000
((100+r)/100)^{2} = (27/25)^{2}
((100+r)/100) = 27/25
100 + r = 108
Rate of interest (r) = 8 %
Incorrect
Answer: c)
Amount = P*(1+(r/100))^{n}
23328 = 20000*(1+(r/100))^{2}
((100+r)/100)^{2} = 23328 /20000
((100+r)/100)^{2} = (27/25)^{2}
((100+r)/100) = 27/25
100 + r = 108
Rate of interest (r) = 8 %
Question 13 of 20
13. Question
A profit of 25 % is made by selling a shirt after offering a discount of 10 %. If the marked price of the shirt is Rs. 1200. Find its Cost price?
Correct
Answer: b)
Marked Price = Rs. 1200
Profit = 25%, Discount = 10%
SP = MP*(90/100)
SP = CP* (125/100)
1200*(90/100) = CP*(125/100)
CP = Rs. 864
Incorrect
Answer: b)
Marked Price = Rs. 1200
Profit = 25%, Discount = 10%
SP = MP*(90/100)
SP = CP* (125/100)
1200*(90/100) = CP*(125/100)
CP = Rs. 864

= > x= 280
120 men included to finish the work.
Incorrect
Answer: d)
Men days work
160 56 1
160 32 ½
? 24 ½
Men1*day1/work1 = Men2*day2/work2
160*56/(1/2) = x*32/(1/2)
= > x= 280
120 men included to finish the work.
Question 15 of 20
15. Question
Two stations A and B are 170 km apart on a straight line. One train starts from A at 8 a.m. and travels towards B at 30 km/hr. Another train starts from B at 9 a.m. and travels towards A at a speed of 40 km/hr. At what time will they meet?
Correct
Answer: c)
Both the trains meet at x hours after 8 am,
Distance covered by A in x hours = 30x km
Distance covered by B in (x – 1) hours = 40*(x – 1) km
30x + 40*(x – 1) = 170
30x + 40x – 40 = 170
70x = 210
X = 210/70 = 3
So, both the trains meet after 3 hours
= > 3 + 8 = 11 a.m.
Shortcut:
Incorrect
Answer: c)
Both the trains meet at x hours after 8 am,
Distance covered by A in x hours = 30x km
Distance covered by B in (x – 1) hours = 40*(x – 1) km
30x + 40*(x – 1) = 170
30x + 40x – 40 = 170
70x = 210
X = 210/70 = 3
So, both the trains meet after 3 hours
= > 3 + 8 = 11 a.m.

16. Question
Directions (16 – 20): Study the following information carefully and answer the given questions:
The following pie chart shows the percentage distribution of total number of tourist went for a 6 different cities and the table shows the male and female tourist among them.
Find the difference between the total number of male tourist went to Delhi and Amarnath together to that of total number of female tourist went to Agra and Lucknow together?
Correct
Answer: c)
The total number of male tourist went to Delhi and Amarnath together
= > 6500*(12/100)*(6/13) + 6500*(15/100)*(8/15)
= > 360 + 520 = 880
The total number of female tourist went to Agra and Lucknow together
= > 6500*(18/100)*(4/9) + 6500*(23/100)*(3/5)
= > 520 + 897 = 1417
Required difference = 1417 – 880 = 537
Incorrect
Answer: c)
The total number of male tourist went to Delhi and Amarnath together
= > 6500*(12/100)*(6/13) + 6500*(15/100)*(8/15)
= > 360 + 520 = 880
The total number of female tourist went to Agra and Lucknow together
