Answer» Correct Answer - Option 3 : 3

For a given number xy, divide y by 5 to find the remainder

Divide the power of 2 by 4 i.e 31/4 

⇒ 4 × 7 = 28

∴ Remainder 31 – 28 = 3

∴ A cycle of 3 can be used

⇒ 23/5 = 8/5 or remainder 3      (5 × 1 = 5, 8 – 5 = 3)

∴ The remainder when 231 is divided by 5 is 3
