correct answer is: b) 100190

Explanation

We know, the least number of 6 digits is 1000000 .
If we divide 1000000 by 215 , we get ‘465’ as a quotient and ‘25’ as a remainder.
So that,
If we subtract the remainder ‘25’ from the divisor ‘215’ then we get:
\left(215-25\right)
\rightarrow 190
Now 190 be added to 100000 , then we get:
\left(100000+190\right)
\rightarrow 100190
\therefore The number is 100190 .
Ans: The least number of 6 digits which is exactly divisible by 215 is 100190.
