Directions: Read the following information to answer the question.
Since 653xy is divisible by 2 as well as by 5, so y = 0
Now 653x0 is divisible by 8 so 3x0 is also divisible by 8.
By hit and trial x=6 and x+y = 6
Directions: Read the following information to answer the question.
Answer :9
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.
