1 Answer

Answer :

b

Profit = (S.P of 25 balls) - (C.P of 25 balls) = 1015 - (C.P of 25 balls)

Given that Profit = (C.P of 10 balls)

=> 1015 - (C.P of 25 balls) = (C.P of 10 balls)

=> (C.P of 25 balls) + (C.P of 10 balls) = 1015

=> C.P of 35 balls = 1015

=> C.P of 1 ball=1015 / 35 = Rs. 29

Description : Two stations X and Y are 170 km apart on a straight line. One train starts from X at 6 a.m. and travels towards Y at 25 kmph. Another train starts from Y at 8 a.m. and travels towards X at a speed of 35 kmph. At what time will they meet? a) 11. 30 a.m b) 10.30 a.m c) 11 a.m d) 9 a.m e) 10 am

Last Answer : e Suppose they meet z hours after 6 a.m. Distance covered by X in z hours = 25× z km. Distance covered by Y in (z - 2) hours = 35(z - 2) km. Therefore 25z + 35(z- 2) = 170 60z = 240 x = 4. So, they meet at 10 a.m.
