If CAT is coded as 3-1-20, then DOG is coded as?
Letters are coded by their position in alphabet. C=3, A=1, T=20. Similarly D=4, O=15, G=7.
BOOK is coded as 2-15-15-11. What is the code for BACK?
Position in alphabet: B=2, O=15, O=15, K=11. For BACK: B=2, A=1, C=3, K=11 = 2-1-3-11
If SMART is coded as TNBSU, then BRAIN is coded as?
SMART→TNBSU: S(+1)=T, M(+1)=N, A(+1)=B, R(+1)=S, T(+1)=U. Simple +1 shift. For BRAIN: B(+1)=C, R(+1)=S, A(+1)=B, I(+1)=J, N(+1)=O = CSBJO
