Last Question:

On sports day, if 30 children were made to stand in a column, 16 columns could be formed. If 24 children were made to stand in a column, how many columns could be formed?

1] 20

2] 30

3] 40

4] 50

Answer:

1] 20

You first have to calculate the total number of children. If 30 children stood in 16 columns, there are 480 children present. Thus, to calculate the number of columns that can be formed with 24 children in each, you divide 480/24 = 20.

Last Problem:

Which number is the odd one out?

9678 4572 5261 3527 7768

1.] 7768

2] 3527

3] 4572

4] 9678

5] 5261

Answer:

2] 3527

Here is the deal: The sum of the first two numbers equal the sum of the third and fourth numbers. For example, for the number 9678 – 9 + 6 = 15 and 7 + 8 = 15. This pattern is the same for all numbers except 3527 (where eight which is the sum of 3 + 5 does not equal 9 (the sum of 2 + 7).
