Correct Answer: 10 points
Explanation:
A : B = 100 : 80.
A : C = 100 : 72.
B:C = B/A*A/C = 80/10*100/72 = 10/9 = 100/90 = 100:90
B can give C 10 points
Correct Answer: 80 sec
Explanation:
B runs 45/2mts in 6 sec
B covers 300m in (6*2/45*300)sec =80 sec
Correct Answer: 111.12 meters
Explanation:
A runs 1000 meters while B runs 900 meters and C runs 800 meters.
Therefore, B runs 900 meters while C runs 800 meters.
So, the number of meters that C runs when B runs 1000 meters = (1000 x 800)/900 = 8000/9 = 888.88 meters
Thus, B can give C (1000 - 888.88) = 111.12 meters start
Correct Answer: 20 m
Correct Answer: 28m
Explanation:
A : B = 100 : 75
B : C = 100 : 96.
A : C = (A/B*B/C) = (100/75*100/96) = 100/72 =100:72
A beats C by (100 - 72) m = 28 m.
Correct Answer: 33 sec
Explanation:
B runs 35 m in 7 sec.
B covers 200 m in (7/35*200) = 40sec
B's time over the course = 40 sec.
A's time over the course (40 - 7) sec = 33 sec.
