A LITTLE PRACTICE. A CLEARER NEXT STEP.
Try a question.
Understand a little more.
Choose your class for a five-question practice check, a worked example and a printable mini worksheet with solutions. Everything here opens without an account.

THIS WEEK’S MATHS CHALLENGE · Classes 6–8
A remainder puzzle
Find the smallest positive whole number that leaves remainder 1 when divided by 2, 3 and 4, and is divisible by 5.
Need a hint?
First find numbers that are one more than a multiple of 12.
See the reasoning
25
The number minus 1 must be divisible by 2, 3 and 4, so it is a multiple of their LCM, 12. Candidates are 1, 13, 25, 37, … . The first divisible by 5 is 25.
Practice gives us a starting point.
These short checks sample a few topics and do not cover the full syllabus. Results are for self-practice; they do not predict board marks, JEE ranks or Olympiad results. The teaching plan is discussed after understanding the student’s class, curriculum and needs.
