Which is the highest peak?

A
A

B
E

C
C

D
B

Solution

$$\Rightarrow$$ We form a table from given graph.
$$Mountains$$ $$Height$$
$$(meters)$$
$$A$$ $$8200$$
$$B$$ $$6000$$
$$C$$ $$8600$$
$$D$$ $$7500$$
$$E$$ $$8800$$
$$F$$ $$6500$$
$$\Rightarrow$$ From above table we can see that mountain $$E$$ has highest height $$8800\,meters$$.
$$\therefore$$ $$E$$ is the highest peak.

$$Monday$$ $$9$$
$$Tuesday$$ $$4$$
$$Wednesday$$ $$6$$
$$Thursday$$ $$4$$
$$Friday$$ $$8$$
$$Saturday$$ $$7$$

The picture graph below shows the number of shirts ordered in each size in one week
Which size of shirts were ordered exactly 15 shirts?

A
Small

B
Medium

C
Large

D
Extra Large

Solution

From the given pictograph, small size have 5 symbol.
Given that one symbol represents 3 shirts.
Therefore $$ \displaystyle 5 \times 3 = 15 $$ shirts were ordered of small size.

Directions For Questions

Given above is a bar graph showing the heights of six mountain peaks
Read the above diagram and answer the following

...view full instructions

When the heights of the given peaks are written in ascending order then what is the average of the middle two peaks?

A
7950 m

B
7560 m

C
7650 m

D
7850 m

Solution

The ascending order of heights is
$$6000 m<6500 m<7500m<$$
$$8200m<8600m<8200m.$$
The two middle peaks are $$7500$$ m and $$8200$$ m
Average = $$\displaystyle \dfrac{7500+8200}{2}$$
$$\displaystyle \frac{15700}{2}=7850m $$
Question 5
1 / -0

Which of the following represents data that continuously changes over periods of time?

A
Bar graph

B
Circle graph

C
Histogram

D
Line graph

Solution

Data that is arranged in columns or rows on a worksheet can be plotted in a line chart. Line charts can display continuous data over time, set against a common scale, and are therefore ideal for showing trends in data at equal intervals. In a line chart, category data is distributed evenly along the horizontal axis, and all value data is distributed evenly along the vertical axis

Hence, answer is Line graph

How many more bottles of pickles were exported on Thursday than Tuesday?

A
$$1000$$

B
$$1200$$

C
$$1500$$

D
$$2000$$

Solution

$$1$$ pickle jar $$= 500$$ bottles
So, in the pictograph shows that more bottles of pickles were exported on Thursday than Tuesday
No. of bottles exported on Tuesday $$=5\times 500=2500$$
No. of bottles exported on Thursday $$8\times 500=4000$$
Thus, the more no. of bottles exported on Thursday than Tuesday $$=4000-2500 = 1500$$
