Answer : A
Explanation
Step 1:
Heights of given bars 16, 26
Step 2:
Mean height = $\frac{(16 + 26)}{2} = \frac{42}{2}$ = 21
So height of new bar = 21
Answer : C
Explanation
Step 1:
Heights of given bars 12, 28
Step 2:
Mean height = $\frac{(12 + 18)}{2} = \frac{30}{2}$ = 15
So height of new bar = 15
Answer : B
Explanation
Step 1:
Heights of given bars 16, 22
Step 2:
Mean height = $\frac{(16 + 22)}{2} = \frac{38}{2}$ = 19
So height of new bar = 19.
Answer : D
Explanation
Step 1:
Heights of given bars 14, 26
Step 2:
Mean height = $\frac{(14 + 26)}{2} = \frac{40}{2}$ = 20
So height of new bar = 20
Answer : C
Explanation
Step 1:
Heights of given bars 15, 19
Step 2:
Mean height = $\frac{(15 + 19)}{2} = \frac{34}{2}$ = 17
So height of new bar = 17
Answer : B
Explanation
Step 1:
