Answers :
1) Answer: c)
Abinav’s one day work = (1/24)
Abinav’s 8 day work = 8/24 = 1/3
Remaining work = 1 – 1/3 = 2/3
(2/3)*Yuva’s whole work = 12
Yuva’s whole work = 12*(3/2) = 18 days
(Abinav + Yuva)’s one day work = (1/24) + (1/18) = 7/72
The number of days taken by both of them to complete the work
= > 72/7 days
2) Answer: a)
The investment ratio = 10: 3: 9
The share of Raju, Vikram and Agalya
= > [10*6 + 10*(130/100)*6]: [3*12]: [9*12]
= > 138: 36: 108
= > 23: 6: 18
Total profit = 47’s = 58750
1’s = 58750/47 = 1250
Vikram’s share = 6’s = Rs. 7500
3) Answer: d)
6 men = 8 women
3 men = 4 women
6 men = 12 children
1 men = 2 children
8 men and 12 women and 20 children = 8 men + 9 men + 10 men = 27 men
Men           days          hours

27              ?                 10
(6*60*8) = (27*x*10)
X = (6*60*8)/(27*10) = 96/9 = 10 (6/9) = 10 (2/3) days
4) Answer: b)
Let the principle amount and rate of interest be x and r respectively,
SI = PNR/100
According to the question,
= > [x*6*(r + 8)]/100 – [x*6*r]/100 = 19200
= > 6xr/100 + 48x/100 – 6xr/100 = 19200
= > 48x/100 = 19200
= > x = (19200*100)/48 = Rs. 40000
5) Answer: d)
The ratio of present age of A to that of the age of B, after 4 years = 5: 7 (5x, 7x)
Present age of A and B = 5x, 7x – 4
C = B – 2 = 7x – 4 – 2 = 7x – 6
The average present age of A, B and C together = 41 years
Total age of A, B and C = 41*3 = 123 years
According to the question,
= > 5x + 7x – 4 + 7x – 6 = 123
= > 19x – 10 = 123
= > 19x = 133
= > x = 7
Present age of C = 7x – 6 = 43 years
Direction (6-10) :
6) Answer: a)
The average MSP of Maize and Pulse together in the year 2017
= > (1800 + 1600)/2 = 1700
The average MSP of Wheat and Millets together in the year 2018
= > (1800 + 1500)/2 = 1650
Required difference = 1700 – 1650 = Rs. 50
7) Answer: d)
The MSP of Pulse in both the years together
= > 1600 + 2000 = 3600
The MSP of Rice in both the years together
= > 2500 + 3000 = 5500
Required ratio = 3600: 5500 = 36: 55
8) Answer: b)
The average MSP of all the given crops in the year 2018
= > (1800 + 2200 + 1500 + 2000 + 3000)/5
= > 10500/5 = Rs. 2100
9) Answer: c)
The MSP of Wheat in both the years together
= > 1500 + 1800 = 3300
The MSP of Millets in both the years together
= > 1200 + 1500 = 2700
Required % = (3300/2700)*100 = 122.22 % = 122 %
10) Answer: e)
Wheat = > 1500 + 1800 = Rs. 3300
Maize = > 1800 + 2200 = Rs. 4000
Millets = > 1200 + 1500 = Rs. 2700
Pulse = > 1600 + 2000 = Rs. 3600
Rice = > 2500 + 3000 = Rs. 5500
Pulse has third lowest of minimum support rice (MSP).
