**Q 1 - The two bars in a bar graph have heights 16 and 26. What height a new bar should have so that it has the mean height of the two bars?**

### 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

**Q 2 - The two bars in a bar graph have heights 12 and 18. What height a new bar should have so that it has the mean height of the two bars?**

### 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

**Q 3 - The two bars in a bar graph have heights 16 and 22. What height a new bar should have so that it has the mean height of the two bars?**

### 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.

**Q 4 - The two bars in a bar graph have heights 14 and 26. What height a new bar should have so that it has the mean height of the two bars?**

### 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

**Q 5 - The two bars in a bar graph have heights 15 and 19. What height a new bar should have so that it has the mean height of the two bars?.**
