The ratio of two speeds of two trains is 3 to 4. If each of the trains slows its speed 5 km/ hr, what will be the ratio of these two train speeds ?	Pick one
A) 3/4  B) 8/9  C) 18/19  D) 23/24  E) It cannot be determined from the information given
3/4 = 3x/4x   we need to find out (3x+5)/(4x+5) off course we cannot solve this to arrive at any rational number hence It cannot be determined from the information given.
