Question

the cost of feeding 24 goats for 12days is 360naira. find the number of days that 20 goats will be fed with 400naira

Answer 1

24 × 12 × x = 360 ( where X is the cost of one day feeding )

so,
288x = 360
x = 360/288 = 1.25 ( 1 rupee and 25 paise)

cost to feed 20 goats = 20 × y × 1.25 = 400

therefore, 25y = 400
y = 400/25 = 16


therefore the number of days to feed 20 goats is 16 days.
