Directions For Questions

The annual maintenance cost of a machine in a factory over a seven years period is represented in the histogram.

...view full instructions

How much did the maintenance cost decreased in $$1996-1997$$ when compared to $$1997-1998$$?

A
$$1200$$

B
$$1500$$

C
$$2500$$

D
$$4500$$

Solution

From the histogram, the maintenance cost in the year:
$$1995-1996$$ is Rs. $$2000$$
$$1996-1997$$ is Rs. $$3000$$
$$1997-1998$$ is Rs. $$1500$$
$$1998-1999$$ is Rs. $$2500$$
$$1999-2000$$ is Rs. $$4850$$
$$2000-2001$$ is Rs. $$5000$$
$$2001-2002$$ is Rs. $$7200$$.

Then, the maintenance cost decreased in $$1996-1997$$ when compared to $$1997-1998 = 3000 - 1500 = 1500$$ rupees.

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

The architecture student counted the number of bricks in each building in his neighbourhood. How many buildings are there in the interval $$6-20$$?

A
$$2$$

B
$$6$$

C
$$10$$

D
$$14$$

Solution

Number of buildings in interval $$6-10=2$$
Number of buildings in interval $$11-15=2$$
Number of buildings in interval $$16-20=6$$.

Therefore, the total number of buildings in $$6-20=2+2+6$$ $$=10$$.

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

The probability of getting number less than or equal to $$6$$, when a die is thrown once, is

A
An impossible event

B
A sure event

C
An exhaustive event

D
A complementary event

Solution

The probability of getting number less than $$6$$, when a die is thrown once, is a sure event.
Because, once a die is thrown, sample space $$= \{1, 2, 3, 4, 5, 6\}$$
There is a possible event for getting number less than $$6$$ as outcomes can be $$1, 2, 3, 4, 5$$.
Question 6
1 / -0

Use the histogram and find the sum of the number of students studying for $$4 - 5$$ and $$8 - 9$$ hours.

A
5

B
8

C
4

D
2

Solution

From the histogram,
The number of students studying for $$4 - 5$$ $$= 5 $$.
The number of students studying for $$6 - 7$$ $$= 4 $$.
The number of students studying for $$8 - 9$$ $$= 3 $$.

Therefore, the sum of the number of students studying for $$4 - 5$$ and $$8 - 9$$ hours $$= 5 + 3 = 8$$.

Hence, option $$B$$ is correct.
Question 7

Directions For Questions

The histogram represents the number of children entering into a library between different times in a day.

...view full instructions

What is the total number of children entered in to the library between $$0-30$$ hours?

A
$$45$$

B
$$55$$

C
$$100$$

D
$$115$$

Solution

From the histogram,
The number of children entered during $$0-10$$ hours $$= 45$$
The number of children entered during $$10-20$$ hours $$= 55$$
The number of children entered during $$20-30$$ hours $$= 15$$
The number of children entered during $$30-40$$ hours $$= 25$$
The number of children entered during $$40-50$$ hours $$= 85$$
The number of children entered during $$50-60$$ hours $$= 10$$.

Therefore, the total number of children during $$0-30$$ hours $$= 45 + 55 + 15 = 115$$.

Hence, option $$D$$ is correct.
Question 8
1 / -0

The histogram shows the age groups of working women in a city. Find the number of working women in the age group of $$29 - 34$$ years.

A
$$300$$

B
$$230$$

C
$$320$$

D
$$410$$

Solution

From the histogram, the number of working women in the age group:
$$23 - 24$$ years is $$= 120$$
$$25 - 26$$ years is $$=80$$
$$27 - 28$$ years is $$= 110$$
$$29 - 30$$ years is $$= 90$$
$$31 - 32$$ years is $$= 100$$
$$33 - 34$$ years is $$= 130$$.

Therefore, the number of working women in the age group of $$29 - 34$$ years $$= 90 + 100 + 130 = 320$$.

Hence, option $$C$$ is correct.
