Primary Divisonal 2012/7

Unread post by Phlembac Adib Hasan » Thu Dec 11, 2014 1:29 pm

Batul said his marks in math to Nonte. Nonte said four times of that number to Fonte. Fonte replaced the digit $6$ with $5$ and told the number to their parents. If it was $58$ for their parents, what was Batul's mark in math?
