If a horse runs his first lap in 75 seconds, how long will it take the horse to complete three laps?
(1) Each lap the horse's speed decreased 20 percent from the previous lap.
(2) The horse will be racing against another horse whose speed increases 8% each lap and who completes three laps in 225 seconds.
The OA is A.
We need to know the speed or the time taken by the horse in each lap.
Statement 1: the speed relation for each lap is given. SUFFICIENT
Statement 2: data for another horse is given without any link. INSUFFICIENT
Hence, A is the correct answer.
Has anyone another strategic approach to solving this DS question? Regards!
