A. Choice 1 is more profitable than Choice 2
B. Choice 2 is more profitable than Choice 3
C. Choice 3 is more profitable than Choice 1
D. None of the above

Thanks,
Rohit.

My take

1-D) The value with Choice 3 comes out to be 9.5 crores

2-D) Choice 1 = Choice 2 = 11 crores ....Choice 3 = 9.5 crores.....therefore options B,C invalid

3 - B) When M/s James prob increases to 0.7 and coverage decreases to 55% even then its value remains 9.5 crores (<11 crores).

Thanks for the reply. Your answers are correct except for Q.1. Infact I too got 9.5 crores for CHOICE 3, and hence checked (D).

As per the answer key for IIFT 2008, the correct answer for Q.1 is 10.6 crores.

Can you explain your approach to this problem? I mean what exactly is the significance of probability in this problem?

Others are invited to comment too!

Thanks,
Rohit.

Hi Rohit,

For the probability aspect, I am just considering that if the Probability value is greater than 0.5 then the respective company(i.e. Bola/James) will be able to increase their coverage value and if less than 0.5 then vice versa....if u want a more detailed soln then let me know. I will PM you.

Puys, pls shed some light on Q 1
