Explanation: LCM of 5,7 and 15 is 105
Therefore add 4 to LCM =105+4=109
So 109 is the first desired three digit no.
Three digits numbers which upon division by 5,7 and 15,give remainder of 4 are 109,214,319,424,529,634,739,844.
So 9 is the correct option.
Hence proved.

29/4 gives remainder 1 .
So 3^1=3
Hence proved.
Directions: Read the following information to answer the question.
If the three odd numbers are a - 2, a and a + 2, then 3(a - 2) = 3 + 2(a + 2)
so a + 2 = 15.
