a mathematics teacher tabulated the marks secured by 35 students of 8 th class. the average of their marks was 72. if the marks secured by reema was written as 36 instead of 86 then find the correct average marks up to two decimal places.	Choose the most appropriate option:
A) 73.41 B) 74.31 C) 72.43 D) 73.43 E) can not be determined

divide(subtract(multiply(35, 72), subtract(86, 36)), 35)
"correct average = 35 x 72 + ( 86 - 36 ) / 35 ≈ 72 + 1.43 = 73.43 answer d"
