Given that y is the nearest integer of , find the value of ,where [.] denotes greatest common integer.

If [x] denotes, the greatest integer less than or equal to x, then find the value of

A whole number when rounded to the nearest ten is 3000.What is the smallest possible value of this number?Use the number line below to help you.

The ratio of two numbers x and y is 3 : 4. If a is added to x and b is added to y, the ratio becomes 11 : 15. Instead if a is subtracted from x and b is subtracted from y, the ratio becomes 7 : 9. Find the smallest value of b, if a, b, x and y are positive integers.
