which is the least number which when divided by 6,15 and 18 leaves remainder 5

Hi!
Here is the answer to your question.
 
The required number is 5 more than the L.C.M of 6, 15 and 18
∴ L.C.M. of 6, 15 and 18 = 2 × 3 × 3 × 5 = 90
Thus, the required number = 90 + 5 = 95
 
Hope! you got the answer.
 
Cheers!
