(a) 103
(b) 100
(c) 102
(d) 99
Ans.(a)
Sol. In the given code, Z = 1, Y = 2, X = 3, ……, C = 24, B = 25, A = 26.
So, DOLL = 23 + 12 + 15 + 15 = 65 and TOY = 7 + 12 + 2 = 21.
Similarly, SOMEONE = S + O + M + E + 0 + N + E= 8 + 12 + 14 + 22 + 12 + 13 + 22 = 103.
Q10. If SMART is coded as 4 and STUDENT as 6, then what is the code for BEAUTIFUL?
(a) 6

(a) 44
(b) 54
(c) 64
(d) 72
Ans.(b)
Sol. As, A = 2 and 1 × 2 = 2
M = 26 and 13 × 2 = 26
Z = 52 and 26 × 2 = 52
Similarly, BET = (2 + 5 + 20) × 2
= 27 × 2 = 54
