If a number leaves remainder 6 when divided by 7, what is the remainder when 1 is added to it and then divided by 7?
Answer and explanation
Correct answer: 0
Step 1: Write the number as (7q+6). Step 2: Adding 1 gives (7q+7=7(q+1)), so the remainder is 0. Step 3: If the remainder is one less than the divisor and 1 is added, divisibility becomes exact.
