In a kilometer race, A beats B by 100 meters and B beats C by 125 meters. Then A beats C by

25 meters

200 meters

212.5 meters

225 meters

✅ Correct Option: 3

When A runs $1000$ m, B runs $900$ m. When B runs $1000$ m, C runs $875$ m, so while B covers $900$ m, C covers $900\times\frac{875}{1000} = 787.5$ m. Hence A beats C by $1000-787.5 = 212.5$ m.

In a kilometer race, A beats B by 30 seconds and B beats C by 15 seconds. If A beats C by 180 m, then

Match List-I with List-II

List-I	List-II
(A) Time taken by A to run 1 km	(I) 250 seconds
(B) Time taken by B to run 1 km	(II) 45 seconds
(C) Time taken by C to run 1 km	(III) 235 seconds
(D) A beats C by	(IV) 205 seconds

A boat goes downstream at a speed of 18 km/hr and upstream at a speed of 'm' km/hr. The boat travelled 90 km downstream in a river and then returned back taking altogether 12.5 hours. Then which of the following are true ?

A. $m = 12$

B. $m = 15$

C. Speed of water current is 3 km/hr

D. Speed of water current is 1.5 km/hr
