Word Problem #03
Read carefully the word problem and choose the
correct answer.
Milo's father tells him a riddle that goes like this;
"I am a number between 121 and 149. I can be
divided by both 3 and 5. What number am I?

To solve the riddle, identify first which numbers are between 121 and 149. Then, choose which numbers are divisible by 5 and eliminate numbers which does not meet this condition. Numbers that are divisible by 5 should have either 0 or 5 as their last digit. The remaining numbers should be:

125
130
135
140
145

Then, check if the remaining numbers are divisible by 3. The easiest way to determine if a number is divisible by three is to get the sum of its digits and then check if it is divisible by three, like this:

123 = 1 + 2 + 5 = 8 (not divisible by 3)
130 = 1 + 3 + 0 = 4 (not divisible by 3)
135 = 1 + 3 + 5 = 9 (divisible by 3)
140 = 1 + 4 + 0 = 5 (not divisible by 3)
145 = 1 + 4 + 5 = 10 (not divisible by 3)

Therefore, 135 is the answer since it is both divisible by 3 and 5.
