If all the candidates except Ajay and Danish had different marks in DI, and Bala's composite score was less than Chetna's composite score, then what is the maximum marks that Bala could have scored in DI?
Explanation:
2d + 20 < 54 ⇒ d < 17
d ≠ 14, 15, 16, 12, 8 and 5
d can take value 13 or 11 or 9 or 7 or 6 or 4 or 3 or 2 or 1.
For d = 13, the composite score = 46
Thus, Bala could have scored 13 marks in DI.
Therefore, the required answer is 13.
Answer: 13
