work backwards, and assume the smallest possible value for the diminished nut pile. :) that should get you started. Francis Gerard Magtibay · 4 years, 6 months ago

@Francis Gerard Magtibay I got the answer, as you can see in the edited discussion. But I wanted to know the fastest way of solving it, since the method i used required the use of a calculator since large numbers were involved... Rohan Rao · 4 years, 6 months ago

The only thing I could come up with is- Let a be the number of coconuts at first, then \(a = 5b + 1\) \(4b= 5c+1\) \( 4c=5d+1\) and so on.. but that won't help.. will it? Soham Chanda · 4 years, 5 months ago

@Soham Chanda That's all very well, but when you solve the set of 6 or 7 simultaneous linear equations, it leaves you exhausted with the strain of multiplying large numbers and is also quite confusing. It is easy to make a mistake. You will get the answer after, say, 45 minutes. That's all. Rohan Rao · 4 years, 5 months ago
