Check here below
for Detailed Solution for the above questions:
1. Time taken by boat A to travel 200 km =
200/(18-10) = 25 hrs
Time taken by boat B to travel 200 km = 200/(14
– 12) =100 hrs
:. Read different = (100 – 25) = 75 hours
So
the answer is: D
2. Total distance travelled by Shyam =1000
km
Distance covered by boat A = 1000 × (40/100) =
400 km
Time taken by boat A = 400/ (18 – 10) =50
hours
Time taken by boat B = [1000 × (18/100)] / (14
– 12) = 90 hours
Time taken by boat C =[1000 × (26/100)] / (10
– 6) = 65 hours
Time taken by boat D = [1000 × (16/100)] / (14
-10) =40 hours
:. Time taken by Shyam = (50 + 90 + 65 + 40 )
245 hours
So
the answer is: B
3. Speed of
boat C after 40% increase in its speed = 10 × (140/100) = 14 kmph
Speed of stream
after 20% decrease = 6 × (80/100) = 4.8 kmph
Now, time taken
by boat C = 200/(14 - 4.8) = 200/9.2 = 21 ×(17/23) hours
Time taken by
boat previously = 200/(10 – 6) = 200/4 =50 hours
:. Difference =
(50 – 21× 17/23) = 28× 6/23 hours
So
the answer is: A
4. New speed of
boat D = 14 × (110/100) = 15.4 kmph
Time taken to
travel 500 km = 500/(15.4 – 10) = 92.54 ~ 92.6 km
So
the answer is: B
5. Time taken
by boat C = x km/(10 + 6)
Time taken by
boat D = x km /( 10 + 14)
:. Read ratio = (x/16)
: (x/24) = 3 : 2
So
the answer is: E
6. 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
So
the answer is: D
7. 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
So
the answer is: B
8. 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
So
the answer is: D
9. When
Rituraj, Prithusen and Viswamohan 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 [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
So
the answer is: D
10. 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 = 5000 × (11/21) = Rs 26190.47
So
the answer is: B
