Answer»

Average marks in 6 exams = 62

Total marks scored in 6 exams = average marks × number of exams

Total marks scored in 6 exams = 62 × 6 = 372

The targeted average is 66 marks.

Marks to be obtained in total 7 exams to get average of 68 = 66 × 7 = 462

ANIL should score 462 - 372 = 90 marks in 7th exam so that his average marks should be 66.
