In a certain code language, 'FROZEN' is coded as '504' and 'TONSILS' is coded as '756'. How will 'MARINE' be coded in that language?

FROZEN has 6 letters and codes to 504 (6 × 84 = 504, not clean). Checking: sum of positions F+R+O+Z+E+N = 6+18+15+26+5+14 = 84; 84 × 6 = 504. MARINE: M+A+R+I+N+E = 13+1+18+9+14+5 = 60; 60 × 6 = 360. This matches option (d).
