The difference in the sales of cellular phones for the years $$1997$$ and $$1999$$ is?

A
$$500$$ units

B
$$1,000$$ units

C
$$5,000$$ units

D
$$18,000$$ units

Solution

The given graph shows the sale of cellular phones in the years $$1997, 1998, 1999, 2000,2001$$ and $$2002$$.

In the year $$1997$$, the sale of cellular phones is $$48000$$.
In the year $$1999$$, the sale of cellular phones is $$30000$$.

Therefore, the difference in the sales of cellular phones for the year $$1997$$ and $$1999$$ is,
$$48000-30000=18000$$

Hence, the difference in the sales of cellular phones for the year $$1997$$ and $$1999$$ is $$18,000$$ units.
Thus, option $$D$$ is correct.

The pie chart given shows the expenditure of a family on various items and its savings during a year.
Study the pie chart and answer the following questions
If the total annual income of the family is Rs. $$75,000$$, what is the expenditure on children education?

A
Rs. $$9000$$

B
Rs. $$9500$$

C

D
Rs. $$5600$$

Solution

Total annual income of the family is Rs. $$75,000$$.

Thus expenditure is Rs. $$ 9000$$.
Question 7
1 / -0

The pie chart shows the deaths of the road users in a country in the year $$2008$$. If the total number of deaths due to road accidents is $$5700$$, then what is the number of people killed in the accidents who were driving four-wheelers.

A
$$499$$

B
$$397$$

C
$$228$$

D
$$497$$

Solution

Total number of people died $$=5700$$
People who were on four wheelers $$=4$$ percent
So number of people killed who were on four wheeles $$=5700\times \dfrac { 4 }{ 100 } =228$$
So option $$C$$ is correct.
Question 8
1 / -0

The bar graph shows the number of traffic accidents in a country from year $$2000$$ to $$2014$$ . What is the difference between accidents in the year $$2001$$ and $$2004$$.

A
$$60,000$$

B
$$40,000$$

C
$$20,000$$

D
$$45,000$$

Solution

The letter $$k$$ is used to denote $$1000$$

Therefore, Number of traffic accidents in the year $$2001$$ $$=260k$$

$$=260\times1000$$

$$=260,000$$

Number of traffic accidents in year $$2004$$ $$=220k$$

$$=220\times1000$$

$$=220,000$$.

Then, the difference $$=260,000-220,000$$

$$=40,000$$

Therefore, option $$B$$ is correct.
Question 9
1 / -0

Count the tally marks.

A
$$20$$

B
$$100$$

C
$$80$$

D
$$40$$

Solution

There are $$20$$ bundles and each bundle consists of total $$5$$ lines.

Therefore, the total number of lines$$=20\times5=100$$

Hence, the total tally marks is $$100$$.
