Question

When a natural number n is divided by 4, the remainder is 3. What is the remainder when 2n is divided by 4?​

Answer 1

Answer:

N = 4Q + 3, where Q is the quotient. ⟹ Required remainder = 2.

Answer 2

Answer:

N = 4Q + 3, where Q is the quotient. ⟹ Required remainder = 2

Step-by-step explanation:

N = 4Q + 3, where Q is the quotient. ∴ ∴ 2N = 8Q + 6 = 4 × 2Q + 4 + 2 = 4 (2Q + 1) + 2 ⟹ ⟹Required remainder = 2
