Question 1

1. Evaluate the following expression carefully: $1.25 \times 0.08 \times 10.5$

A) 1.05B) 10.5C) 0.105D) 1.50

Answer

✓ Correct Answer: Option A

Explanation: Solution: Step 1: Multiply 1.25 and 0.08. $125 \times 8 = 1000$. With 4 decimal places, $1.25 \times 0.08 = 0.1$. Step 2: Multiply the result by 10.5. $0.1 \times 10.5 = 1.05$.

Question 2

2. A rectangular hall has an area of $48.96 m^2$. If the breadth of the hall is 5.1 m, find the perimeter of the hall.

A) 14.7 mB) 29.4 mC) 24.48 m

Question 3

3. If $234 \times 56 = 13104$, what is the value of $13.104 \div 0.056$?

A) 2.34B) 23.4C) 234D) 2340

Answer

✓ Correct Answer: Option C

Explanation: Solution: Given $234 \times 56 = 13104$, then $\frac{13104}{56} = 234$. $13.104 \div 0.056 = \frac{13.104}{0.056}$. Multiply both parts by 1000: $\frac{13104}{56} = 234$.

Question 4

4. A metal rod of length 15.75 m is cut into 25 equal small pieces. What is the length of each piece in centimeters?

A) 0.63 cmB) 6.3 cmC) 630 cmD) 63 cm

Answer

✓ Correct Answer: Option D

Explanation: Solution: Length in meters $= 15.75 \div 25 = 0.63 m$. To convert to cm: $0.63 \times 100 = 63 cm$.

Question 5

5. Express the sum of $3 \frac{7}{125}$ and $2 \frac{4}{25}$ as a decimal.

A) 5.216B) 5.116C) 5.056D) 5.28

Answer

✓ Correct Answer: Option A

Explanation: Solution: $3 \frac{7}{125} = 3 + \frac{56}{1000} = 3.056$. $2 \frac{4}{25} = 2 + \frac{16}{100} = 2.16$. Sum = 3.056 + 2.160 = 5.216.

Question 6

6. A car travels 16.5 km using 1 litre of petrol. How many litres of petrol will be required to cover a distance of 338.25 km?

A) 2.05 litresB) 25 litresC) 20.5 litresD) 21.5 litres

Answer

✓ Correct Answer: Option C

Explanation: Solution: $Petrol required = 338.25 \div 16.5 = 20.5 litres$.

Question 7

7. What must be added to the product of 0.12 and 0.5 to get 1?

A) 0.88B) 0.94C) 0.06D) 0.96

Answer

✓ Correct Answer: Option B

Explanation: Solution: $Product = 0.12 \times 0.5 = 0.06$. x + 0.06 = 1 ⇒ x = 1 - 0.06 = 0.94.

Question 8

8. Solve: $(0.2)^3 + (0.3)^2 - 0.05$

A) 0.013B) 0.14C) 0.098D) 0.048

Answer

✓ Correct Answer: Option D

Explanation: Solution: $(0.2)^3 = 0.008$. $(0.3)^2 = 0.09$. 0.008 + 0.09 - 0.05 = 0.098 - 0.05 = 0.048.

Question 9

9. A vessel contains 4.5 litres of milk. If 0.75 litres of milk is poured into each of several small bottles, how many bottles are filled?

A) 5B) 8C) 6D) 60

Answer

✓ Correct Answer: Option C

Explanation: Solution: $Number of bottles = 4.5 \div 0.75 = 450 \div 75 = 6$.

Question 10

10. Which of the following is equal to $0.007 \times 10^3 + 0.7 \div 10^2$?

A) 7.007B) 0.707C) 70.07D) 7.07

Answer

✓ Correct Answer: Option A

Explanation: Solution: $0.007 \times 1000 = 7$. $0.7 \div 100 = 0.007$. Sum = 7 + 0.007 = 7.007.

Accepted Answer

✓ Correct Answer: Option B

Explanation: Solution: $Length = Area \div Breadth = 48.96 \div 5.1 = 9.6 m$. Perimeter = 2(Length + Breadth) = 2(9.6 + 5.1) = 2(14.7) = 29.4 m.
