In a certain code, '3245' means 'you must study hard', '567' means 'hard work pays', and '614' means 'work and study'. Which of the following are the codes for 'pays' and 'work' respectively?

A1 and 5

B5 and 6

C7 and 6 ✓ Correct

D4 and 5

Correct answer: (C) 7 and 6

Explanation

'pays' is 7 and 'work' is 6.

'3245' and '567' share only 'hard', matching digit 5.

'567' and '614' share only 'work', matching digit 6.

In '567', with hard = 5 and work = 6, the leftover 7 is 'pays'.

So 'pays' = 7 and 'work' = 6.
