Amit Garg
- Feb 13th, 2015
Answer is = 204.
Here is the logic
single box= 8x8
double boxes=7x7
three boxes =6x6 ....
and so on till eight boxes = 1x1 = 1
so 64+49+36+25+16+9+4+1 = 204 -
(x to power 1/3) - (x to power 1/9)=60 We have to find out the value of x ??
ragav
- Dec 12th, 2007
Let x to power 1/9 = tthen, t^3- t = 60t^3 >> t (except for t=1)therefore,t^3 is approximately = 60Therefore , t = 4 and x=4^9= 262144

The answer for this question is, there are 300 chickens and 60 days. by
solving the eqs
xy = (x-75)*(y+20).....................(1)
xy = (x+!00)*(y-15).....................(2)
Let x be the no. of chickens and the days be y
