Question

The avarage weight of 10 apples is 52 gram. Leter it was found that the apple weighing mechine had shown the weight of each apple 10 gram more. The correct avarage weigh of an apple​

Answer 1

Answer:

average is equal to weight of all apples by total number of apples so the average weight of apples is equal to x/10=52(x is weight of 10 apples) so the weight of 10 apples will be 520. Since reading of each apple was 10g more so the total increase in weight will be 10*10=100. So add this to the earlier weight of apples which is 520. So the new total weight will be 620. so average weight will be 62 grams after substituting the values in the formula
