52

152

158

264

To make the number sentence 158 = ___ + 106 correct, we need to find the missing number that, when added to 106, equals 158. The missing number is 52 because 106 + 52 = 158.

Explanation

To make the number sentence 158 = ___ + 106 correct, we need to find the missing number that, when added to 106, equals 158. The missing number is 52 because 106 + 52 = 158.

2) Faizal has 918 marbles. He wants to make packets of marbles, with nine marbles in each pack. How many packs will he be able to make?

12

102

120

1062

Faizal has 918 marbles and wants to make packets of 9 marbles each. To find the number of packs he can make, we divide the total number of marbles by the number of marbles in each pack. Therefore, 918 divided by 9 equals 102. So, Faizal will be able to make 102 packs of marbles.

Explanation

Faizal has 918 marbles and wants to make packets of 9 marbles each. To find the number of packs he can make, we divide the total number of marbles by the number of marbles in each pack. Therefore, 918 divided by 9 equals 102. So, Faizal will be able to make 102 packs of marbles.

3) A teacher brought some toffees to her class. After giving three toffees each to 15 students who had completed their assignments, she has 60 toffees left with her. How many toffees did she bring to the class?

15

45

78

105

The teacher gave three toffees each to 15 students, which means she gave away a total of 3 x 15 = 45 toffees. If she has 60 toffees left after giving away 45, then she must have brought 45 + 60 = 105 toffees to the class initially.

Explanation

The teacher gave three toffees each to 15 students, which means she gave away a total of 3 x 15 = 45 toffees. If she has 60 toffees left after giving away 45, then she must have brought 45 + 60 = 105 toffees to the class initially.

4) Which of these numbers have only two factors, 1 and the number itself?

37+1

37+37

37X1

37X37

The number 37X1 has only two factors, 1 and the number itself. This is because when a number is multiplied by 1, it remains the same. Therefore, the only factors of 37X1 are 1 and 37X1 itself, making it the correct answer.

Explanation

The number 37X1 has only two factors, 1 and the number itself. This is because when a number is multiplied by 1, it remains the same. Therefore, the only factors of 37X1 are 1 and 37X1 itself, making it the correct answer.

5) 1024+1025+___=1025+1025+1025 What number will come in the blank to make the number sentence correct?

1024

1025

1026

5124

The number that will come in the blank to make the number sentence correct is 1026. This is because when we add 1024, 1025, and 1026 together, we get a sum of 3075. On the other side of the equation, when we add 1025, 1025, and 1025 together, we also get a sum of 3075. Therefore, to balance the equation, the missing number must be 1026.

Explanation

The number that will come in the blank to make the number sentence correct is 1026. This is because when we add 1024, 1025, and 1026 together, we get a sum of 3075. On the other side of the equation, when we add 1025, 1025, and 1025 together, we also get a sum of 3075. Therefore, to balance the equation, the missing number must be 1026.

6) John has stamps from different countries. 1/3rd of them are India stamps. if he has 36 Indian stamps, how many stamps does he have in total?

12

36

48

108

If 1/3 of John's stamps are Indian stamps and he has 36 Indian stamps, it means that the total number of stamps he has is three times that amount. Therefore, 36 x 3 = 108.

Explanation

If 1/3 of John's stamps are Indian stamps and he has 36 Indian stamps, it means that the total number of stamps he has is three times that amount. Therefore, 36 x 3 = 108.

7) Meena divides a number by 2. She then divides the answer by 2. This is the same as dividing the original number by:

1

2

4

Cannot be said as the original number is not known.

When Meena divides a number by 2 and then divides the answer by 2 again, it is equivalent to dividing the original number by 4. This is because dividing a number by 2 is the same as multiplying it by 1/2, and dividing the result by 2 again is the same as multiplying it by 1/2 again. When you multiply 1/2 by 1/2, you get 1/4, which means dividing the original number by 4. Therefore, the correct answer is 4.

Explanation

When Meena divides a number by 2 and then divides the answer by 2 again, it is equivalent to dividing the original number by 4. This is because dividing a number by 2 is the same as multiplying it by 1/2, and dividing the result by 2 again is the same as multiplying it by 1/2 again. When you multiply 1/2 by 1/2, you get 1/4, which means dividing the original number by 4. Therefore, the correct answer is 4.

8) Which of these lies between 6.3 and 6.6?

6.2

6.9

6.05

6.41

6.41 lies between 6.3 and 6.6 because it is greater than 6.3 and less than 6.6.

Explanation

6.41 lies between 6.3 and 6.6 because it is greater than 6.3 and less than 6.6.

9) Shown below is a part of a triangle with one of its angles missing. The measure of the missing angle is:

90

Less than 90

More than 90

(we cannot say any of the above definitely.)

Based on the given information, we can determine that the missing angle is more than 90 degrees. This is because a triangle has a total of 180 degrees, and if one angle is 90 degrees or less, the remaining angles must add up to more than 90 degrees in order to reach a total of 180 degrees. Therefore, we can conclude that the missing angle is more than 90 degrees.

Based on the given information, we can determine that the missing angle is more than 90 degrees. This is because a triangle has a total of 180 degrees, and if one angle is 90 degrees or less, the remaining angles must add up to more than 90 degrees in order to reach a total of 180 degrees. Therefore, we can conclude that the missing angle is more than 90 degrees.

10) Meena has bought six pens. The cost of each pen was between Rs.25 and Rs. 30. Which of these could be the total cost of the pens?

Rs.55

Rs.126

Rs.173

Rs.330

Since Meena has bought six pens and the cost of each pen is between Rs.25 and Rs.30, the minimum possible total cost would be 6 x Rs.25 = Rs.150 and the maximum possible total cost would be 6 x Rs.30 = Rs.180. Out of the given options, Rs.173 falls within this range and could be the total cost of the pens.
