Question

if the mean score of 12 students in maths is 5 and the mean score of another 10 students is 6. Calculate the average score of 22 students to the nearest whole number​

Answer 1

the answer is 5.(5+6) divided by 2=5.5

Answer 2

the nearest whole number​: 5

Explanation:

(12 x 5) + (10 x 6) = 120

120 / 22 = 5.45

since the first digit of the fractional part is 4, that's less than 5.

So the nearest whole number is 5
