(1)3
(2)6
(3)7
(4)8
(5)10

Removing OA as am not able to use the spoiler

N= 3x6x9x18x.....99
so the value of 10 could be calculated by calculating no. of 10's 30, 60, 90
[spoiler]so Ans (1) 3[/spoiler]

Shashank you at least missed 15*even number + 45*even number + 75*even number [spoiler]which make it 6[/spoiler]

oh yes sorry I missed the numbers which could multiply by even number and give us a multiple of 10 ..thanks deepak
15, 45, 75
also 75 has two 5's i.e. it will give 2 values.
30,60,90 is already there
so total values = 3 + 3 +1 =[spoiler]7 Ans (3)[/spoiler]

Thanks shashank this 75 containing two 5s was something i was missing OA is 7.But unfortunately I am still not able to use spoiler

yeah deepak I actually missed a lots of 5 first time...so I did a detailed analysis and found out every hidden 5 ...so I think ans matches with OA of source..
