Correct Answer: L
Solution : Given: J = 1, K = 2, L = 5, M = 7, N = 11, O = 13, P = 17 (N × ? + M) ÷ K = 31
After replacing the letters with numbers, the equation we get is – ⇒ (11 × ? + 7) ÷ 2 = 31 ⇒ (11 × ? + 7) = 62 ⇒ 11 × ? = 62 – 7 ⇒ 11 × ? = 55 ⇒ ? = 5
So, the letter that is coded as 5 is L. Hence, the first option is correct.
