  Let speed of trains = v ,Speed of Basanti = b ,Relative speed of first train wrt Basanti = v-b ,Relative speed of second train wrt Basanti = v+b ,Distance travelled by first train in 8 minutes = distance travelled by second train in 6 minutes (by using relative speed) ,(v-b)*8 = (v+b)*6 ,V = 7b ,Let the time interval between two trains from pune is “x” , 7b*(8-x) = 8*b, X = 48/7
