If the arithmetic mean of 0, 5, 4, 3 is a, that of -1, 0, 1, 5, 4, 3 is b and that of 5, 4, 3 is c, then the relation between a, b, and c is
Answer & Solution
Correct Answer:
Option
B
We have :
$$\eqalign{ & a = \frac{{0 + 5 + 4 + 3}}{4} = 3 \cr & b = \frac{{ - 1 + 0 + 1 + 5 + 4 + 3}}{6} = 2 \cr & c = \frac{{5 + 4 + 3}}{3} = 4 \cr & \therefore a:b:c = 3:2:4 \cr} $$
$$\eqalign{ & a = \frac{{0 + 5 + 4 + 3}}{4} = 3 \cr & b = \frac{{ - 1 + 0 + 1 + 5 + 4 + 3}}{6} = 2 \cr & c = \frac{{5 + 4 + 3}}{3} = 4 \cr & \therefore a:b:c = 3:2:4 \cr} $$
