Answers:
1). Required number = (45525 × 36)/100 = 16389
Answer is: b)
2). Number of women liking
Total = 155050
Required average= 155050/8
=19381.25 = 19381
Answer is: e)
3). Number of men liking DD = 45% of 56340
= (45 × 56340)/100 = 25353
Number of men liking PPN = 15% of 355080
= (15 × 355080)/100 = 5337
Required percentage
= (25353/5337) × 100 = 475.04%
Answer is: b)
4). Required percentage = (Number of women liking PP /Number of women liking all teams) × 100
= (21252/155050) × 100
= 13.8%
Answer is: e)
5). Required ratio = (36800 × 39)/100 : (48300 × 21)/100
= 14352 : 10143
= 208 : 147
Answer is: c)
6). Answer: d)
Part of building construction by Rituraj in one day = 1/20 by Amarkant = 1/22 and by Prithusen = 1/24
Work of building construction done in 1 day by all three together= (1/20 + 1/22 + 1/24) = 181/1320
ie, they construct a building in 1320/181 = 7 (53/181) days
7).Answer: b)
The part of work of tower installation done by Vishwamohan in one day = 1/24, that Laliteshwar in one day = 1/30 and that by Rituraj in one day = 1/26
The part work of tower installation done by all three together in one day
=1/24 + 1/30 + 1/26 = 177/1560
:. 1 tower installation work is done in 1560 /177 days
:. 10 tower installation work is done in (1560 ×10)/177 = 88.13 days
8). Answer: d)
The part of work of bridge construction done by Rituraj, Prithusen and Laliteshwar in 4 days
= (1/24 + 1/30 + 1/26) × 4 = (177 × 4) / 1560 = 708/1560 =59 / 130
The part of work of bridge construction done by Rituraj, Prithusen and Amarkant in one day
= (1/24 + 1/30+ 1/20) = (5 + 4 + 6)/120 = 1/8
After 4 days the remaining work = 1- (59/130) = (130 – 59)/130 = 71/130
Now, 71/130 work is done by Rituraj, Prithusen and Amarkant in
(71/130) / (1/8) = (71 × 8)/130= 568/130 = 4 (24/65) days
9). Answer: d)
When Rituraj, Prithusen and Vishwamohan work together, the work of building construction done by them =
(1/20 + 1/24 + 1/18) = 53/360
Per day work of road construction =
(1/18 + 1/22 +1/26) = 359/2574
53/360 part of building construction work is done in 1 day.
5 buildings are constructed in [360/53) × 5] = 33.96 days
359/2574 part of road construction is done in 1 day.
4 roads are constructed in [2574/359) × 4] = 28.67 days
:. Total time taken = (33.96 + 28.67) = 62.63 days
10). Answer: b)
Ratio of work done by Rituraj to that by Amarkant in one day in building construction
Or, Rituraj: Amarkant = 1/20 : 1/22 = 11 : 10
Total wage = 500000
:. Share of Rituraj = 50000 × (11/21) = Rs 26190.47
