B. 25.56 %
C. 50.25%
D. 54.25%v

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let the marked price = Tk. 100
Then, SP = 100 - 20% of 100 = Tk. 80
Profit = 25%
Let His CP = X
SP = 80
X + 25% of X = 80
Hence, X = Tk. (100 × 80)/125
= Tk. 64
CP = Tk. 64
Profit after selling on marked price = 100 - 64 = Tk. 36
% gain = (36 × 100)/64
= 56.25%

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

D. 55 km/hr

View Answer	Favorite Question	Report

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.

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

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