Answer / anil
Ans. is 2519.
we have to multiply all numbers from 2-10 keeping aside
common number.
i.e.
2*3*4*5*7*3 = 2520
6 is left b'coz 2*3 is 6
9 = 3*3 hence, 3 is taken twice.
At last 2520-1.

Answer / sudhanshu_kmr
According to the question when the number is divided by 2,3,..10 leaves remainder 1,2,...9 respectively. It means that if we increase the that number by 1 then it is divisible by each of the numbers 2,3,..10.
So, find a number that is common divisor of 2,3,4,...and 10.
And subtract 1 from it.
LCM of 2,3,..10 is 2520.
2520-1 = 2519
thus, 2519 is the required number.......
