Q. 1: The second question in ET was prepared by:
1. Chetan
2. Esha
3. Beti
4. Dave
Correct Answer: Option 4
Explanation:
As both MT and ET has atleast 4 questions of 5 marks, atleast 3 ques of 10 marks, and 2 questions of 15 marks
Marks covered by these = 5×4 + 10×3 + 15×2 = 80
Marks left = 20
20 can be divided as (5,5,5,5) (5,5,10) (5,15) (10,10)
Order of question = 5 marks, 10 marks, 15 marks
Since it is given that 5th question is a 5 mark question case of 10,10 marks is rued out
As everyone prepared an equa number of questions the number has to be a factor of 6 greater than 18 and the only possible number here is 24.
Hence the only possible cases are (5,5,5,5) (5,15)Thus ET has 13 questions and MT has 11 questions
Now all the question can be answered.
