What fractional part of the race remains?

Let's take a look at the explanation of the riddle.

As per the total laps in the race are 50 and the driver has completed 12 1/2 laps. This means, we have to subtract 12 1/2 from the total 50 laps. This equal to 37 1/2 or 37.5

50 - 12 1/2 = 37 1/2 or 37.5

Now, we need to calculate the fractional part of the race remains. For this, we need to divide the remaining laps by total laps, that is, 37 1/2 divide by 50 or 37.5 divided by 50 which will be equal to 0.74 or 3/4.

37 1/2 / 50 = 0.74 or 3/4

70

15 + 1x1 = 16

16 + 2x2 = 20

20 + 3x3 = 29

29 + 4x4 = 45

45 + 5x5 = 70
