c) Rs 24130.5
d) Rs 22990.7
e) Rs 28970.5
1). Answer: a)
Total distance travelled by Mohit = 1500 km
Distance covered by Boat B1 =1500×(38/100) = 570 km
Time taken by Boat B1= 570/(20-14) = 285/3 = 95 hrs
Distance covered by Boat B2 = (20/100)×1500 = 300 km
Time taken by Boat B2= 300/(16-14) = 150 km
Similarly, time taken by Boat B3 = (24×15)/(12-8) = 90 hrs
Time taken by Boat B4 = (18×15) / (16-10) = 45 hrs
Total time taken by Mohit = 95+150+90+45 = 380 hrs
2). Answer: c)
Speed of B3= 12+8 = 20 kmph
Speed of B4 = 16+10 = 26 kmph
Time taken by Boat B3 = 360/20
Time taken by Boat B4= 270/26
Required ratio = 18×(26/270) = 26:15
3). Answer: a)
New speed of Boat B4
= 16×(115/100) = 18.4 kmph
Time taken to travel 756 km
= 756/(18.4-10) = 756/8.4 = 90 hrs
4). Answer: a)
Time taken by Boat B1
= 300/(20-14) = 300/6 = 50 hrs
Time taken by Boat = 300/(16-14) = 300/2
Required difference = 150-50=100 hrs
5). Answer: c)
Speed of boat B3 after 30% increase in its speed = 12×(130/100) = 15.6 kmph
Speed of stream after 15% decrease = 8×(85/100) = 6.8 kmph
Now, the time taken by Boat B3
= 440 / (15.6-6.8) = 50 hours
Time taken by boat B3 previously (Before increase in speed)
= 440 / (12-8) = 110 hrs
Difference = 110 – 50 = 60 hrs
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
