Question

The world record for long jump is 8.95 mts by Mike Powell, record for long jump in Europeans is 8.86 mts by Robert Emmiyan, and the record in Olympic is 8.90 mts by Bob Beamon. Among all the one who holds the longest jump is

  1. Mike
  2. Robert
  3. Bob
  4. Mike and Bob

Hint:

Try to compare all the records starting from most significant digit to list significant digit and select maximum .

The correct answer is: Mike


Step 1 : Compare first two
8.95 by Mike Powell and 8.86 by Robert
8 and 8 first digits of both the numbers are same.
9 and 8, so Mike Powell.
Step 2 : compare result of previous with current left,
8.95 by Mike Powell and 8.90 by Bob
8 and 8 first digits are same.
9 and 9, second digits are same.
5 and 0, so Mike Powell.
So, Mike Powell holds the record with a jump of 8.95 mts.

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

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.

The heights of the students of grade 4 are as follows:
Albert – 3.8 feet
Patrick – 3.5 feet
John – 3.0 feet
Adam – 3.10 feet
Jacob – 3.6 feet
For the selection of students for the long jump, Selectors asked them to stand in a line according to their heights in decreasing order (the tallest being the first participant). The student standing fourth in the line would be

GIVEN-
Heights of students-
Albert – 3.8 feet
Patrick – 3.5 feet
John – 3.0 feet
Adam – 3.10 feet
Jacob – 3.6 feet
TO FIND-
Student standing in 4th position when arranged in decreasing order of heights.
SOLUTION-
We will first arrange heights of the given students in decreasing order-
3.8, 3.6, 3.5, 3.10, 3.0.
Hence, 4th position = 3.10 feet.
Hence, when arranged in decreasing order of heights, the person on 4th position among the given set of people is Adam with a height of 3.10 feet.
FINAL ANSWER-
Option 'c' i.e. 'Adam' is the correct answer to the given question.
