D
0.2860915

Solution

0.0036584 + 0.00025847 x 100 - 0.000896250
Applying BODMAS
-> 0.00025847 x 100 = 0.025847
-> 0.025847 + 0.0036584 = 0.0295054
-> 0.0295054 - 0.000896250 = 0.2860915

A
26.35

B
25.54

C
23.34

D
22.22

Solution

Let the other number be x.

x + 15.87 = 42.22

x = 42.22 - 15.87

x = 26.35
Question 12
1 / -0

Which of the following bars is the longest?

A
B

B
A

C
D

D
C

Solution

Length of bar A = 4 - 0 = 4 cm

Length of bar B = 5.0 - 0.5 = 4.5 cm

Length of bar C = 4 - 1 = 3 cm

Length of bar D = 3.5 - 0 = 3.5 cm

Thus, bar B is the longest one.
Question 13
1 / -0

What is the value of (12.123 + 12.2 + 12.34) rounded to the nearest tenth?

A
36.3

B
36.5

C
36.7

D
36.9

Solution

12.123 + 12.2 + 12.34 = 36.663

To round the number to the nearest tenth, we look at the digit at the hundredths place.

Now, since the digit at the hundredths place is 6, the tenths place digit would be rounded up to 7.

So, the answer is 36.7.

Question 21
1 / -0

Kiran buys three different pieces of cloth having different lengths. The lengths are 12 m 25 cm, 9 m 12 cm, 65 m 12 cm. The total length of all the pieces of cloth is

A
86.49 m

B
88.12 m

C
87.12 m

D
86.34 m

Solution

Three different lengths:

12 m 25 cm == (12 + 0.25) m = 12.25 m

9 m 12 cm == (9 + 0.12) m
= 9.12 m

65 m 12 cm =
= (65 + 0.12) m

= 65.12 m

Total length = 12.25 + 9.12 + 65.12 = 86.49 m
Question 22
1 / -0

Rohan had Rs. 815.75 with him and he bought books worth Rs. 215.50. How much money would be left with him?

A
Rs. 555.12

B
Rs. 600.25

C
Rs. 650.50

D
Rs. 712.65

Solution

Total money = Rs. 815.75

Money spent = Rs. 215.50

Money left = 815.75 - 215.50

= Rs. 600.25
Question 23
1 / -0

Bob went to work using two different means of travel. He travelled 4 km and 15 m by auto, and 8 km and 45 m by bus. Find the total distance travelled in km.

A
12.06

B
12.52

C
13.15

D
13.28

Solution

Distance covered by auto = 4 km and 15 m

= 4 + (15 ÷ 1000) km

= (4 + 0.015) km

= 4.015 km

Distance covered by bus = 8 km and 45 m

= 8 + (45 ÷ 1000) km

= (8 + 0.045) km

= 8.045 km

Total distance covered = 4.015 + 8.045

= 12.06 km
Question 24
1 / -0

Kunal had Rs. 200 with him. He gave Rs. 14.45 to two of his friends each, Rs. 21.45 to three of his friends each, and Rs. 18.34 to another two of his friends each. Find the total amount of money left with him.

A
Rs. 70.07

B
Rs. 65.34

C
Rs. 60.12

D
Rs. 55.75

Solution

Amount had initially Rs. 200.

According to the question,

Amount given = (14.45 x 2) + (21.45 x 3) + (18.34 x 2)

= 28.9 + 64.35 + 36.68

= Rs. 129.93

Amount left = Rs. 200 - Rs. 129.93 = Rs. 70.07
Question 25
1 / -0

A college purchases books for the library. The cost of 65 books is Rs. 4865.35. Find the cost of one such book.

A
Rs. 80.12

B
Rs. 74.85

C
Rs. 71.12

D
Rs. 66.15

Solution

Cost of 65 books = Rs. 4865.35

Cost of 1 book = Rs. (4865.35 ÷ 65)

= Rs. 74.85
Question 26
1 / -0

Fill in the blanks.

(i) 21 hundredths = 2 tenths + _____ hundredths

(ii) 34.999 rounded to the nearest tenth is equal to ______.

(iii) The fractionis equal to ______.

A

(i) (ii) (iii)

1 36 12.23

B

(i) (ii) (iii)

1 40 12.23

C

(i) (ii) (iii)

1 35 12.23

D

(i) (ii) (iii)

2 35 13.23

Solution

(i) 21 hundredths == 0.21 = 2 tenths + 1 hundredths

(ii) If we look at the hundredths place value column, it is 9, which is more than 5; thus, the digit at the tenths columns will round up and 9 will become 0. Thus, the answer is 35.000 or 35.

(iii)= =
== 12.23
Question 27
1 / -0

State 'T' for true and 'F' for false.

(i) The decimal representation ofis 0.13.

(ii) 0.6 is the same as 0.60.

(iii) is greater than 0.3.

A

(i) (ii) (iii)

F T T

B

(i) (ii) (iii)

T T T

C

(i) (ii) (iii)

F T F

D

(i) (ii) (iii)

F F F

Solution

(i) means 13 tenths and since 10 has one zero, so the number 13 will move to the right by 1 place. Thus, it is the same as 1.3.

(ii) Zeros after the decimal point do not matter. Thus, 0.6 and 0.60 are same.

(iii) can be written asor two tenths.
2 tenths = 0.2, which is smaller than 0.3.

Question 28

1 / -0

Match the following:

Column I	Column II
(i) 12.45 + 1.22 + 15.4	(a) 2.58
(ii) (15.65 + 45.77) - 12.22	(b) 29.07
(iii) 17.12 - 5.55 - 8.99	(c) 65.8
(iv) 35.56 + (87.11 - 56.87)	(d) 49.2

(i) (ii) (iii) (iv)

(b) (a) (d) (c)

(i) (ii) (iii) (iv)

(c) (d) (a) (b)

(i) (ii) (iii) (iv)

(d) (b) (a) (c)

(i) (ii) (iii) (iv)

(b) (d) (a) (c)

Solution

(i) 12.45 + 1.22 + 15.4 = 13.67 + 15.4 = 29.07

(ii) (15.65+45.77) - 12.22 = 61.42 - 12.22 = 49.2

(iii) 17.12 - 5.55 - 8.99 = 11.57 - 8.99 = 2.58

(iv) 35.56 + (87.11 - 56.87) = 35.56 + 30.24 = 65.8

Question 29
1 / -0

Select the INCORRECT statement.

(a) Anil has Rs. 50 with him. He spends Rs. 18.65 on toys. He is now left with Rs. 31.35.
(b) A person walks 345 m on Monday, 234 m on Tuesday and 515 m on Wednesday. He walks 1.094 km altogether.
(c) A person has Rs. 500.50 with him. He gives Rs. 125.25 to his son and Rs. 315.50 to his daughter. He is left with Rs. 59.75.
(d) There is a 1 litre bottle. A boy pours 513.57 ml of lemon juice in it and 405.43 ml of orange juice. He is able to fill the bottle completely.

A
(a)

B
(b)

C
(c)

D
(d)

Solution

(a)Money he has = Rs. 50
Money spent = Rs. 18.65
Money left = Rs. (50 - 18.65) = Rs. 31.35

(b) Total distance travelled = (345 + 234 + 515) m = 1094 m = (1094 ÷ 1000) km = 1.094 km

(c) Money he has = Rs. 500.50
Money given to son = Rs. 125.25
Money given to daughter = Rs. 315.50
Total money given = Rs. (125.25 + 315.50) = Rs. 440.75
Money left = 500.50 - 440.75 = Rs. 59.75

(d) Amount of lemon juice= 513.57 ml
Amount of orange juice = 405.43 ml
Total = 919 ml or 0.919 l (1 l = 1000 ml)
So, he hasn't filled the bottle completely. This statement is INCORRECT.
Question 30
1 / -0

Study the following statements carefully and choose the correct option.

Statement 1: (4.25 + 6.78 + 1.22) > (9.55 - 1.23 + 6.89)
Statement 2: The product of two decimal numbers is same even if the order is reversed.

A
Both statements 1 and 2 are true.

B
Only statement 1 is true.

C
Only statement 2 is true.

D
Both statements 1 and 2 are false.

Solution

For statement 1:

4.25 + 6.78 + 1.22 = 12.25

9.55 - 1.23 + 6.89 = 15.21

12.25 < 15.21

So, statement 1 is false.

Statement 2 is true. It is called distributive property of decimals.
