Answer : 1. "48 kmph"
Explanation :
Answer: A) 48 kmph Explanation: Let the initial speed of Akhil be '4p' kmph Then speed after decrease in speed = '3p' kmph We know that, Change in speed == Change in time According to the given data, 243p - 244p = 35 - 2560=> p = 12 Hence, the initial speed of Akhil = 4p = 4 x 12 = 48 kmph.

If it had run in the opposite direction, it would hit by the train 2m before the end of the bridge. What is the lenght of the bridge in meters assuming the speed of the train is 4 times that of cow ? 94734 35b5cc705e4d2b4197774f249

Answer : 3. "32 mts"
Explanation :
Answer: C) 32 mts Explanation: let 'b' be the Length of bridge from cow to the near end of the bridge and 'a' be the distance of the train from the bridge. 'x' be speed of cow => '4x' speed of trainThen the total length of the bridge 2b + 10.(a-2)/4x = b/x=> a-2 = 4b........(1)Now if it had run in opposite direction(a+2b+10-2)/4x = (b+10-2)/x=> a - 2b = 24......(2)Solving (1) and (2)b = 11 , Therefore length of the bridge is 2 x 11 + 10 = 32mts.
