A number consists of two digits and the digit in the ten's place exceeds that in the unit's place by 5. If 5 times the sum of the digits be subtracted from the number, the digits of the number are reversed. Then the sum of the digits of the number is:

The number which can be written in the form of n (n+1) (n+2), where n is a natural number, is:

The number will be, whose square is equal to the difference between the squares of 975 and 585, is:

Direction : What value should come in the place of question mark (?) in the following questions?

$$ \sqrt{8281} =(?) $$

The average of some natural numbers is 15. If 30 is added to first number and 5 is subtracted from the last number, the average become 17.5. then the numbers of natural numbers is :
