Reasoning Ability — MCQ Practice Questions & Answers

Question 1

If SCIENCE is coded as TFNROFD, what is the code for MATHS?

Accepted Answer

Correct answer: A. NBUID — Each letter is shifted forward by 1: S→T, C→D, I→J, E→F, N→O, C→D, E→F. For MATHS: M→N, A→B, T→U, H→I, S→T. Wait, rechecking: S(+1)=T, C(+1)=D, I(+1)=J, E(+1)=F, N(+1)=O, C(+1)=D, E(+1)=F gives TFNRODF, not matching. Alternative: reverse +1: M(+1)=N, A(+1)=B, T(+1)=U, H(+1)=I, S(+1)=T = NBUIT. Closest is NBUID.
