A) 240 B) 360
C) 420 D) 600
 
Answer & Explanation Answer: C) 420

Explanation:

Initially                 CP           profit            SP                MP

 

                              100           x               (100+x)         133.33

 

After Change     100           2x             (100+x)   

 

Now,   Since (100+x)  - 100 = 2x

 

           76 x= 20%

 

                         CP            Profit              SP             MP

 

                        100             20               120           133.33

 

So,                  300             60               360             400

 

Again             300            120              420

 

So the increased selling price = Rs. 420

Q:

Two trains having equal lengths, take 10 seconds and 15 seconds respectively to cross a post. If the length of each train is 120 meters, in what time (in seconds) will they cross each other when traveling in opposite direction?

A) 10 B) 25
C) 12 D) 20
 
Answer & Explanation Answer: C) 12

Explanation:

Speed of train 1 = 12010m/sec = 12 m/sec 

Speed of train 2 =12015m/sec  = 8 m/sec 

if they travel in opposite direction, relative speed = 12 + 8 = 20 m/sec

distance covered = 120 + 120 = 240 m

time = distance/speed = 240/20 = 12 sec
