The line graph gives the percentage increase in the number of students and the fee per student at a coaching institute, across five years. The increase in values for each year is with respect to that of the previous year.

Solution:

The number of students in 2011 = \(\cfrac{29.375×10}{12,500}\)  = 23,500

Number of students in 2013 = 23,500 × 1.06 ×  1.02 = 25408

Fee collected per student in 2013 = 12,500 ×  1.12×  1.09 =15260

Total fee collected = 38.77 cr

The number of students in 2011 =(3+7=10)% of 29.375/12500 = 23,500

Number of students in 2013 = 23,500 × 1.06 × 1.02 = 25408

(since, 6% increase in 2012 and 2% increase in 2013, so 23500 is multiplied by 1.06 and 1.02)

Fee collected per student in 2013 = 12,500 × 1.12× 1.09 =15260

Total fee collected = 38.77 cr
