Three men rent a farm for Rs 7000 per annum A puts 110 cows in the farm for 3 months

A:B:C=110*3:110*6:440*3 = 3:6:12 = 1:2:4

share of A = 1/(1+2+4) * 7000 = 1000

% expenditure of A = 1000/7000 *100 = 100/7 = 14.28%

Let Us consider the rent to keep 1 cow for 3 months be x ,
then for A 110x, for B 220x ("for 2 months"),for C 440x
therefore A:B:C = 110x:220x:440x
Simplifying it- A:B:C=1:2:4
Now payement for A=7000*1/7=1000
percentage of A- (1000/7000)*100=(1/7)*100= 14.28%

a's exp ratio is :
(a's investment * a's time)/ ((b's inv* b's time )*(c's inv * c's time))
110*0.25/ (110*0.5 + 440*0.25)
= 27.5/55 +110
1/6
=16.66%

1*3:1*4:4*3
21=7000
a percentage of total expenditure is 1000*100/7000=14.28%;

(110*3):(110*6):(440*3)
330:660:1320.
So. A share is 7000*(1/7)=1000.
But we need to find the percentage. So, (1000/7000)*100=14.28%
