#LRDIoftheDay #32 A set on sequential data

The following Table gives the number of students in all the different classes of Indian Public school in the years 2050 and 2051 respectively.

It is known that

i. New students join the school only in class VII

ii. No student leaves the school before passing out from class XII

iii. The students, who fail, have to repeat the year.

1. If no student of class XI failed in the year 2050, then what is the pass percentage of class XII for the year 2050? (Write your answer accurate up to 2 places after the decimal. Eg. If your answer comes out to be 14.2857, it will be 14.29)

2. If the new joiners in the year 2051 were 76, then what is the number of students who failed in class XII in the year 2050?

3. How many students of class IX failed in the year 2050, if no student of class XI failed in the year 2050?

4. If the number of students of class VII who failed in the year 2050 is 64, then what is the total number of students failed in the year 2050?

5. What can be the highest pass percentage of class VII? (If your answer is say 99%, write 99 in the text box)
