The letters L, M, N, O, P, Q, R, S, T in their order are substituted by nine integers 1 to 9 in that order. 4 is assigned to P. the difference between P and T is 5. The difference between N and T is 3. What is the integer assigned to N?

6

Integer assigned to P = 4

⇒ the difference between P and T is 5

So, Integer assigned to T = 5 + 4 = 9

⇒ The difference between N and T is 3

So, Integer assigned to N = 9 - 3 =6

Answer  = (B)  6
