Question
In a marathon, Bucky completed the race in 1 hr 12 min 24 sec, Roger finished the race in 1 hr 10 min 12 sec, Tony finished in 1 hr 12 min 20 sec and Chadwick finished it in 1 hr 10 min 24 sec. If the results were ranked fastest to slowest, then the one who stands medal less is
- Bucky
- Roger
- Tony
- Chadwick
Hint:
Arranging the numbers in decreasing order of their values is called descending order.
The correct answer is: Bucky
Here, we are given the timings of 4 boys who completed a race. We have to find the boy who will not win a medal.
The timings of Bucky, Roger, Tony and Chadwick are 1 hr 12 min 24 sec, 1 hr 10 min 12 sec, 1 hr 12 min 20 sec and 1 hr 10 min 24 sec respectively.
The values arranged in descending order is 1 hr 12 min 24 sec, 1 hr 12 min 20 sec, 1 hr 10 min 24 sec and 1 hr 10 min 12 sec.
Since, Bucky took the highest time to finish the race. So, he will be medal less.
Hence, the correct options is A.
In descending order, the number with the highest value is written first, the number with value lesser than the highest is written in second place and so on.
