Question 1
1 / -0

The histogram shows that the level of diabetic (in mg per dl) of $$105$$ children. How many children have a level of diabetic between $$100-120$$?

A
$$15$$

B
$$10$$

C
$$20$$

D
$$35$$

Solution

By referring the histogram, number of students with diabetic level:
$$20-40$$ is $$5$$ students
$$40-60$$ is $$20$$ students
$$60-80$$ is $$35$$ students
$$80-100$$ is $$15$$ students
$$100-120$$ is $$10$$ students
$$120-140$$ is $$20$$ students.

Therefore, $$10$$ children have a level of diabetic between $$100-120$$.

Hence, option $$B$$ is correct.

How many employees get to work in less than $$60$$ minutes?

A
$$10$$

B
$$5$$

C
$$15$$

D
$$20$$

Solution

From the histogram, we can observe the class width of:
$$0-20$$ minutes $$= 4$$ employees,
$$20-40$$ minutes $$= 6$$ employees,
$$40-60$$ minutes $$ = 10$$ employees.

Therefore, number of employees get into work in less than $$60$$ minutes $$= 4 + 6 + 10 = 20$$.

So, $$20$$ employees get into work less than $$60$$ minutes.

Hence, option $$D$$ is correct.

Directions For Questions

The number of ducks at each pond in the Mumbai city is shown in the histogram.

...view full instructions

How many number of ducks are there in less than $$60$$ ponds?

A
$$59$$

B
$$39$$

C
$$29$$

D
$$19$$

Solution

From the histogram, the class width gives the number of ducks:
$$0 - 19 = 30$$ number of ponds.
$$20 - 39 = 20$$ number of ponds.
$$40 - 59 = 25$$ number of ponds.
$$60 - 79 = 10$$ number of ponds.
$$80 - 99 = 20$$ number of ponds.
$$100 - 119 = 15$$ number of ponds.

Therefore, $$30+20+25=59$$ number of ducks are there in less than $$60$$ ponds.

Hence, option $$A$$ is correct.
Question 4
1 / -0

Directions For Questions

$$70$$ number of student's heights are measured in cm as shown in the histogram.

...view full instructions

How many students have heights less than $$180$$ cm?

A
$$40$$

B
$$63$$

C
$$38$$

D
$$53$$

Solution

From the histogram, the frequency associated with the class width is as follows:
$$120 - 140$$ is $$4$$
$$140 - 160$$ is $$10$$
$$160 - 180$$ is $$24$$
$$180 - 200$$ is $$10$$
$$200 - 220$$ is $$15$$
$$220 - 240$$ is $$7$$.

Therefore, number of students who have heights less than $$180$$ cm $$= 24 + 10 + 4 = 38$$.

Hence, option $$C$$ is correct.
Question 5
1 / -0

$$70$$ number of student's height are measured in cm as shown in the histogram. How many students have heights more than $$180$$ cm?

A
$$40$$

B
$$63$$

C
$$38$$

D
$$32$$

Solution

The given histogram represents the height of $$70$$ students in $$cm$$.

For finding the number of students having a height of more than $$180\ cm$$, we need to add the heights of the bars representing the bars $$180-200,\ 200-220,\ 220-240$$
The height of the bar, representing the number of students is:
$$180-200\rightarrow 10$$
$$200-220\rightarrow 15$$
$$220-240\rightarrow 7$$

Therefore, number of students having height more than $$180\ cm= 10 + 15 + 7$$
$$ = 32$$

Hence, $$32$$ students have height more than $$180\ cm$$.
Question 6

Directions For Questions

The number of ducks at each pond in the Mumbai city is shown in the histogram.

...view full instructions

In which class interval number of ducks is equal to $$20$$ ponds?

A
$$0-19$$ and $$80-99$$

B
$$19-39$$ and $$80-99$$

C
$$20-39$$ and $$80-99$$

D
$$40-59$$ and $$100-119$$

Solution

From the histogram, the class width of number of ducks:
$$0 - 19 = 30$$ number of ponds.
$$20 - 39 = 20$$ number of ponds.
$$40 - 59 = 25$$ number of ponds.
$$60 - 79 = 10$$ number of ponds.
$$80 - 99 = 20$$ number of ponds.
$$100 - 119 = 15$$ number of ponds.

Therefore, $$20-39$$ and $$80-99$$ is the two class interval equal to $$20$$ ponds.

Hence, option $$C$$ is correct.

How many employees get to work in less than $$20$$ minutes?

A
$$4$$

B
$$6$$

C
$$10$$

D
$$15$$

Solution

From the histogram, we can observe the class width of:
$$0-20$$ minutes $$= 4$$ employees.

Therefore, the number of employees get into work in less than $$20$$ minutes $$= 4$$.
So, $$4$$ employees get into work less than $$20$$ minutes.

Hence, option $$A$$ is correct.
Question 8

Directions For Questions

$$70$$ number of student's heights are measured in cm as shown in the histogram.

...view full instructions

How many students have heights less than $$220$$ cm?

A
$$40$$

B
$$63$$

C
$$48$$

D
$$53$$

Solution

From the histogram, the class width of number of students:
$$120 - 140$$ is $$4$$
$$140 - 160$$ is $$10$$
$$160 - 180$$ is $$24$$
$$180 - 200$$ is $$10$$
$$200 - 220$$ is $$15$$
$$220 - 240$$ is $$7$$.

Therefore, the number of students having heights less than $$220$$ cm $$= 15 + 10 + 24 + 10 + 4 = 63$$.

Hence, option $$B$$ is correct.

How many bottles of pickles were exported on Friday and Tuesday altogether?

A
$$4500$$

B
$$1500$$

C
$$5000$$

D
$$5500$$

Solution

$$1$$ pickle jar $$= 500$$ bottles
Friday $$= 6 \times 500 = 3000$$
Tuesday $$= 5 \times 500 = 2500$$
Altogether $$= 3000 + 2500 = 5500$$.

Directions For Questions

Amit, Bala, Frank, Madesh, Thomas are officers. The pictograph shows the earnings of five officers in a month. Use the information from the graph to answer the questions.

Subtracting two of the officers earnings, the difference is $$1800$$. The name of officers are

A
Amit and Bala

B
Frank and Thomas

C
Thomas and Amit

D
Amit and Madesh

Solution

Given: Subtracting two of the officers earnings, the difference is $$1800$$.
Amit $$= 6$$
Thomas $$= 2$$
So, the difference $$= 6 - 2 = 4$$
1 money bag $$= 450$$
Then, $$4 \times 450 = 1800$$
Therefore, the two officers are Thomas and Amit.
