If (a=7q+5), what is the remainder when (3a) is divided by (7)?

Answer and explanation

Correct answer: (1)

Step 1: The remainder of (a) is (5), so for (3a), check (3 \times 5=15). Step 2: (15=7 \times 2+1), so the remainder is (1). Step 3: In such questions, work with the remainder instead of the whole number.
