A Correct answer
Explanation

This is the correct option. The pattern followed here is that the position at which the letter occurs is divided by 2. Thus, F is 6/2 = 3, H is 8/2 = 4 and so on. Thus, D(4) + R(18) + U(21) + M(13) = 4 + 18 + 21 + 13 = 56/2 = 28. Then, J(10) + U(21) + G(7) = 10 + 21 + 7 = 38/2 = 19.

D Correct answer
Explanation

This is the correct option. The pattern followed here is that the value of C = 4, D = 5, E = 6 and so on. The value of D(5) + O(16) + L(13) + L(13) = 47. Thus, the value of L(13) + E(6) + F(7) + T(21) = 47
