Question

In an English test, the score of  4 pupils are 79, 76, 93 and 85. Mariel obtained 7 marks more than the average score of the 4 pupils. What is Mariel’s score in the English test?

 

____________

our answer for this qn is 90.25 but the answer sheet states 92. 

Answer

This is a Quantity Each Product  question. 

   Quantity Each    Product
4 person 4 83.25 333
5 person  5 85 425

 333 ÷ 4 = 83.25

83.25 + 7/4 = 85

425 – 333 = 92

😊

Note

7 mark more than the average means 7/4 + average,

not 7 + average.
