Hi coolboyx12;

Edit: On re-reading the question, I've come to the conclusion that I don't understand the question at all! So maybe you should ignore what I wrote in the hide bar.

I'll think about it some more, but there seems to be some critical info missing...

Re: arithmetical question, please help.

Back again...

What exactly does the phrase 'he got a claim of damages' mean?

My first understanding was that he'd received a bill from a repairer to fix Rs. 750,000 worth of damages, but I see now that it could mean that he'd lodged an insurance claim and been paid that amount by the insurer.

I have other Qs about the wording rattling around in my head, but they may change depending on the answer I get to the above.

Hi phrontister;

the answer is 719,512.5, look at Ganesh's post.

Re: arithmetical question, please help.

Thanks, coolboyx12.

So I've looked at ganesh's method, and have some comments about it:

A. Depreciation:
The problem doesn't mention depreciation, nor its percentage, but ganesh's method includes a yearly fixed depreciation rate of 10%, applied to 3 years.
   1. There seems to be no generally-used standard regarding the amount of vehicle depreciation: instead, the depreciation percentage depends on many factors, such as the make and model of the vehicle, its age and its use (eg, private or business).
   2. Vehicle depreciation rates are not necessarily fixed (eg, diminishing rates).
   3. If we assume that depreciation applies, it's important to know when it takes effect: eg, whether it's at the beginning, or at the end, of each year (often a vehicle's value depreciates immediately a person takes possession of it). If applied at the start of each year, it should be applied in each of the 4 years, not just the first 3 (the damages claim was in year 4).

B. Insurance premiums:
There are 4 insurance terms ('After 3 years he got a claim of damages'), but ganesh's method only charges for 3.
   
Another thing unclear to me is the huge discrepancy between the initial worth of the vehicle (Rs. 450,000) and the subsequent 'claim of damages' (Rs. 750,000).

To me, it implies that the initial worth (unadjusted over time) was simply used as a basis for premium calculation, and that the insurance policy actually covered a higher amount.

Re: arithmetical question, please help.

Hi ganesh & coolboyx12;

I've redone my work (using Excel tables this time), with calculations as per the options named in the hide buttons below:

Both options include scenarios for insurance premiums charged for 3 days and for 4 days.
