Question 74

The mean of a, b, c, d and e is 36. If the mean of b, d and e is 32, what is the mean of a and c?

Solution

The mean of a, b, c, d and e is 36. The mean of b, d and e is 32

Total of a, b, c, d and e $$=36\times5 = 180$$

Total of b, d and e $$=32\times 3 =96$$

Mean of a and c = $$\frac{180-96}{2} = 42$$

Option C is correct.
