TELL ME A FIVE DIGIT NUMBER WHEN DIVIDED BY 2 TO 10
REMAINDER IS 1 AND WHEN DIVIDED BY 11 REMINDER IS 0.
i.e.., FIVE DIGIT NUMBER DIVIDED BY 2 GIVES REMINDER OF 1,
FIVE DIGIT NUMBER DIVDED BY 3 GIVES REMINDER OF 1 AND SO ON
TILL 10, THEN THE SAME FIVE DIGIT NUMBER DIVIDED BY 11
GIVES A REMINDER OF ZERO.

Answer / arthi
Lets say the number is x.
X-1 is divisible by all numbers from 1 to 10.
To find the smallest number that satisfies x, find the LCM - lowest common multiple - of 1 to 10. (hope you know to find it)
=2*3*2*5*7*2*3=2520
but 2520 is only 4 digits, so we need to find a multiple of 2520, so that when you add 1 it is divisible by 11 ie
2520*a + 1 = 11*y
by trial and error, you find that a is 10, so the number is 2520*10 +1 = 25201 .

It would depend on the nature of the question, whether they need all the numbers, or at least one.
