In a certain code language, 'SCAR' is coded as '2386' and 'RACE' is coded as '8642'. What is the code for 'E' in the given code language?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 4
The digits are not written in the order of the letters (read in order, R would be 6 in SCAR but 8 in RACE), so the code is found by comparing the letters and digits the two words share.
SCAR: letters S, C, A, R — digits 2, 3, 8, 6
RACE: letters R, A, C, E — digits 8, 6, 4, 2
Common letters: R, A, C; common digits: 2, 8, 6. So R, A and C stand for 2, 8 and 6 in some order.
The letter left in SCAR is S, and the digit left is 3, so S = 3.
The letter left in RACE is E, and the digit left is 4, so E = 4.
