In a certain code language SORT is coded as 2169, TEST is coded as 5122, DOG is coded as 368 and GOAT is coded as 6243. What will be the code of ROAST in the same language ?
Answer c.
Explanation Answer · c
Option c: only 21946 contains exactly the digits assigned to R, O, A, S and T. The codes identify digit sets rather than preserving letter order. TEST shows T=2; comparing SORT and TEST gives S=1 and E=5. SORT and DOG share only O, giving O=6; then R=9. DOG and GOAT give G=3, D=8 and A=4. ROAST therefore needs the digits 9,6,4,1,2; only option c contains exactly that multiset.
