❄Question❄

Sixty students were there in a mental ability test. Ten students did not qualify, out of remaining

Yogesh ranked 25th from the last. What was his rank from top?

\large\bf\red{❄\:Answer\:❄}❄Answer❄

Required Answer:-

Total number of students = 60.

Number of failed students = 10

Then,

Number of passed students = 60 - 10 = 50

The ranking must be done for the passed students. So, we have a total of 50 students who qualified and ranked from top to bottom.

Now,

Yogesh ranked 25th from the last. Then his rank from the top will be::

Total number of students + 1 - Rank from the bottom.

It is because, the position from the top and the bottom will be counted 2 times. Hence, we have to add one more, since we are determining the position from top.

➙ 50 + 1 - 25

➙ 51 - 25

➙ 26th

Hence:-

Yogesh is 26th from the top of the class.
