In below question, in explanation it is mentioned " estimate at start of project would be USD 50 Mn".

Does this mean that, we should find out estimate at start and not use "50 Mn" given is Question?

I went through the link but it does not answer my query.

My doubt is "Does this mean that, we should find out estimate at start and not use "50 Mn" given is Question?"

Appreciate additional inputs from you. Thanks!

Hi Vikram question has provided you both the information.

ROM range of USD 30 Mn to USD 70 Mn - one can use the range to calculate initial estimate

or use 50 MN which is already provided in the question

you can get question with either of the information.

I tried to calculate initial estimate (ROM) using -25% and +75%. But, I get initial estimate as 40 Mn instead of 50 Mn. My calculation as below:

Let us assume initial estimate as x Mn.

x - 0.25x = 30 --> 0.75x = 30 --> x = 40

x + 0.75 x = 70 --> 1.75x = 70 --> x = 40

Request you to verify and provide your inputs

Thanks!

### Re: Q - Cost Estimation

Same with me. I too didn't get the calculation on how that 50M comes by looking at 30M and 70M as ROM, could anyone please elaborate?vikram_unde wrote:Thanks Manish,manishpn wrote:Hi Vikram question has provided you both the information.
