Question 1:
In a 100m race, A can beat B by 25m and B can beat C by 4m. In the same race, A can beat C by A. 29m
B. 21m
C. 26m
D. 28m
Feedback A :B = 100:75 and B :C = 100:96
A :C = (A/B * B/C ) = (100/75*100/96 ) = 100/72 = 100:72
So, A beats C by (100-72) m = 28m
A :C = (A/B * B/C ) = (100/75*100/96 ) = 100/72 = 100:72
So, A beats C by (100-72) m = 28m
