Answer 1

Thanks for the day free points

Answer 2

Answer:

There are 100 blocks in a colony numbering 1 to 100

A school van stops at every 6th block and but at every 10th block this is biased on LCM property. So, find LCM of 6 and 10.

LCM of 6 and 10=2×3×5=30.

Firstly both will stop at 30th block, then at 6th block and lastly st 90th blocks.
