Answer: Option B

Explanation:

The correct option is C 400 rupees
Let C.P. of article be x rupees. Then,
(105% of x)−(80% of x)=100
⇒25% of x=100
⇒x=400
So, C.P. =400 rupees

1202 . A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds. The speed of the second train is --

A. 66 km/hr
B. 54 km/hr
C. 48 km/hr
D. 82 km/hr

View Answer	Favorite Question

Answer: Option D

Explanation:

ধরি, দ্বিতীয় ট্রেনটির গতি x km/hr

6/60× 60 = (108/1000) + (112 /1000) / x + 50

1/600 = ( 220/1000) / x + 50

1/600 = 22/100( x + 50)

1/6 = 22/ x + 50

x + 50 = 6 × 22

x = 132 - 50

x = 82

View Answer	Favorite Question

Answer: Option B

Explanation:

Given:

Length of train = 125 m

Time taken = 10 secs

Speed of man = 5 km/hr

Concept Used:

When 2 objects are moving in same direction, then

Relative speed = Difference between their speeds

Formula Used:

Speed = Distance/Time

1 Km/hr = (5/18)/s

Calculations:

Let the speed of train be v km/hr.

Speed of the man = 5 km/hr

Now, (v-5) × (5/18) = (125/10)

বা, (v-5) = (125/10) × (18/5) = 45 km/hr

বা, v = (45+5)= 50 km/hr.

D. 130 s

View Answer	Favorite Question

Answer: Option B

Explanation:

Given:

Length of the train = 240 m

Time taken to cross the pole =24 s

Length of the platform = 650 m

Concept Used :

Time take into cross the platform = (length of train + length of the platform)/speed of the train

Speed of train = length of train/time taken

Calculation:

Speed of train = 240/24 = 10 m/s

Time taken to cross the platform = (240 + 650)/10 = 890/10
= 89 s

:The time taken to cross the platform is 89 s.

Hints : The train requires. 24 seconds to pass its length

Hence its speed is = 240 /24 m/s = 10 m/s

To pass 650m long platform it will pass total ( 650 + 240) or 890 m

So, time requires = 890/ 10 sec = 89 sec

A. 360
B. 500
C. 540
D. 130

View Answer	Favorite Question

Answer: Option B

Explanation:

78 km/hr = (78 × 1000) / 60 m/min = 1300 m/min

In 1 minute it travels 1300 m/min

1300 = 800 + length of tunnel

length of tunnel = 1300 - 800 = 500 merer.

Answer: Option C

Explanation:

ধরি, গাড়ির গতিবেগ x কিমি / ঘন্টা

ট্রেনের গাড়ির ( x + x × 500/100) = 3x/2 ঘন্টা

75x/x - 75/3x/2 = 12.5/60

75/x - 150/3x = 125/600

225 - 150 /3x = 125/600

125 × 3x = 600 × 75

x = 600 × 75 /125 × 3

x = 120
