The average of 4 quantities is 5. The average of 2 them is 6. What is the average of the remaining two numbers?

The average of 4 quantities is 5.

Therefore,the sum of the 4 quantities is 4 Ã— 5 =20.

The average of two of these 4 quantities is 6.

Therefore, the sum of these three quantities = 2 Ã— 6 = 12

The sum of the remaining two quantities = 20 - 12 = 8.

Average of these two quantities = 8 / 2 = 4.

In following number series, two terms have been put within brackets. Choose the appropriate option

Choose the appropriate option 2, 3, (6), 11, 18, (30), 38

Choose the appropriate option 2, 3, (6), 11, 18, (30), 38

The correct sequence is + 1, + 3, + 5, + 7, + 9, + 11.

Clearly, the term 6 is correct,

But, 30 is wrong and should be replaced by (18 + 9) i.e. 27.
