Test: High Order Thinking Skills - 2 - Class 4 MCQ

To solve this question, let’s analyze both statements:

• Statement P: The number 456 rounded off to the nearest tens. When rounding to the nearest tens, we look at the digit in the units place (6 in this case). Since it is 5 or more, we round up the tens place. Thus, 456 becomes 460. P is true.
• Statement Q: The sum of the digits in the number 327 is calculated by adding 3 + 2 + 7 = 12. This sum is correct. Q is true.

So, the correct answer is Option C: Both P and Q are true.

Let’s analyze both statements:

• Statement P: The product of 9 and 8 is 72 because multiplying 9 by 8 gives us 72. P is true.
• Statement Q: The number 321 rounded to the nearest hundred. The digit in the tens place is 2, which is less than 5, so we round down the hundred place. Therefore, 321 rounded to the nearest hundred becomes 300. Q is true.

So, the correct answer is Option C: Both P and Q are true.

Let’s check both statements:

• Statement P: The number 843 rounded to the nearest tens involves checking the units place (3 in this case). Since 3 is less than 5, we round down, making it 840. P is true.
• Statement Q: The difference between 50 and 23 is calculated by subtracting 23 from 50, which gives 27. Q is true.

So, the correct answer is Option C: Both P and Q are true.

To solve this, let's look at each part of the question:

• Part (i): The place value of 7 in the number 57254 is 7000 (because it is in the thousands place). The face value of 7 is simply 7. The difference between the place value and the face value is 7000 - 7 = 6993.
• Part (ii): The number 20853 rounded to the nearest hundreds involves checking the tens place, which is 5. Since the digit in the tens place is 5 or more, we round up the hundreds place. Therefore, 20853 becomes 20900 when rounded to the nearest hundreds.

So, the correct answer is Option B: 6993 and 20900.

To solve this, let's look at each part of the question:

• Part (i): The place value of 4 in the number 64125 is 4000 (because it is in the thousands place). The face value of 4 is simply 4. The sum of the place value and face value is 4000 + 4 = 4004.
• Part (ii): The number 67489 rounded to the nearest thousands involves checking the hundreds place, which is 4. Since the digit in the hundreds place is less than 5, we round down the thousands place. Therefore, 67489 becomes 67000 when rounded to the nearest thousands.

So, the correct answer is Option D: 4004 and 67000

Part (i): The place value of 5 in the number 95862 is 5000 (because it is in the thousands place). The face value of 5 is simply 5. The difference between the place value and face value is 5000 - 5 = 4995.

Part (ii): The number 34278 rounded to the nearest hundreds involves checking the tens place, which is 7. Since the digit in the tens place is 5 or more, we round up the hundreds place. Therefore, 34278 becomes 34300 when rounded to the nearest hundreds.

So, the correct answer is Option A: 4995 and 34300.

Part (i): The place value of 3 in the number 73812 is 3000 (because it is in the thousands place). The face value of 3 is simply 3. The sum of the place value and face value is 3000 + 3 = 3003.

Part (ii): The number 98654 rounded to the nearest thousands involves checking the hundreds place, which is 6. Since the digit in the hundreds place is 5 or more, we round up the thousands place. Therefore, 98654 becomes 99000 when rounded to the nearest thousands.

So, the correct answer is Option C: 3003 and 99000.

Total number of equal parts = 8
(i) Number of parts colored with red color = 3
So, required fraction = 3/8
(ii) Number of parts colored with blue color = 2
Number of parts colored with green color = 3
So, required fraction = 2/3

(i) On Wednesday, maximum number of food packets were distributed.
(ii) Number of food packets that were distributed on Thursday and Friday together = 2000 + 1500  = 3500
So, required difference = 3500 – 2500 = 1000

Figure (P):

Perimeter = (2 + 4 + 4 + 2 + 4 + 4 + 4 + 2 + 4 + 2 + 2 + 10) cm = 44 cm
Figure (Q):

Perimeter = (3 + 2 + 4 + 4 + 2 + 4 + 8 + 4 + 3 + 6) cm = 40 cm
So, required difference = 44 cm – 40 cm = 4 cm
