Q3. Supposing that telegraph poles on a railway track are 50 metres apart. How many pole will be passed by a train in 2 hours. If the speed of the train is 45 km/hr

1801
1800
1601
1600
Solution:

 Distance travelled by train in 2 hours = 45 × 2 = 90 kms = 90000 m
No. of pole passed = 90000/50+1
= 1800 + 1
= 1801 poles

Q4. A train 150 metre long, passes a pole in 15 seconds and another train of the same length travelling in the opposite direction in 12 seconds. The speed of the second train is 

45 km/hr
48 km/hr
52 km/hr
54 km/hr
Solution:

When distance is same, speed is indirectly proportional to the time
Speed of the first train = 150/15 = 10 m/s
Speed of the second train = 10/12×15
= 150/12 m/s
=150/12×18/5
= 45 km/hr

Q5. A, B and C are partners in a business. A, whose money has been used for 4 months, claims 1/8 of the profit, B whose money has been used for 6 months, claims 1/3 of the profit. C had invested Rs. 1560 for 8 months. How much did A and B contribute? 

Rs. 740, Rs. 1250
Rs. 730, Rs. 1240
Rs. 720, Rs. 1280
Rs. 750, Rs. 1260
Solution:

C’s share =1-(1/8+1/3)=13/24
C’s investment = 1560 × 8
If 13/24=1560×8
 Then, 1/8=(1 ×1560 ×8 ×24)/(8 ×13)
= 120 × 24
A’s share is for 4 months 

∴ 120 × 24 = 120 × 6 × 4
A’s share = 120 × 6 = 720
 B’s share =1/3=(1 ×1560 × 8 × 24)/(3 ×13)
= 120 × 8 × 8
 B’s share is for 6 months
120 × 8 × 8 = 20 × 6 × 8 × 8
 B’s share = 20 × 8 × 8 = 1280
