Q11. If CAT is coded as 3120, then DOG is ?
Answer: 4157
Explanation: Letters position C=3,A=1,T=20 so D=4,O=15,G=7 gives 4157. Work each step carefully; ISSB math rewards accuracy under time pressure.
Q12. If PENCIL is 653421, then PEN is ?
Answer: 653
Explanation: Use letter to digit mapping from the word pencil. Work each step carefully; ISSB math rewards accuracy under time pressure.
Q13. If MOON is 13151514, then SUN is ?
Answer: 192114
Explanation: S=19, U=21, N=14 so SUN is 192114. Work each step carefully; ISSB math rewards accuracy under time pressure.
Q14. If RED=27 and BLUE=42, pattern value of GREEN?
Answer: 57
Explanation: Letter position sums R+E+D=27 similarly GREEN G+R+E+E+N=57. Work each step carefully; ISSB math rewards accuracy under time pressure.
Q15. If 2@3=8 and 3@4=15, rule a@b=a×b+1. Then 4@5=?
Answer: 21
Explanation: Four times five plus one equals twenty one. Work each step carefully; ISSB math rewards accuracy under time pressure.
Q16. If TABLE=20, CHAIR=?, using letter count×2 for TABLE T+A+B+L+E=5×2=10 wrong. Simple: word length×4 for TABLE=5×4=20. CHAIR length 5×4=20
Answer: 20
Explanation: TABLE has 5 letters times 4 equals 20 so CHAIR 5 times 4 is 20.
Q17. If FISH=6198, then SHIP=?
