Marked Price = 500 + 40% of 500 = ₹700.

Selling Price after 20% discount = 700 - 20% of 700 = ₹560.

Profit = 560 - 500 = ₹60.

Profit percentage = (60/500) × 100 = 12%.

Let distance = d km.

Time for A to B = d/60 hours, Time for B to A = d/40 hours.

Total time: d/60 + d/40 = 10.

Taking LCM: (2d + 3d)/120 = 10, so 5d/120 = 10, giving d = 240 km.

This is a straightforward application of distance-speed-time relationship.
