Verified by Experts

let us assume the consumption of rice in 18 days to be x kgs.
the more the period of time, the more is the consumption of rice, hence the proportion is a direct proportion.
`therefore` (ratio of number of days) : :(ratio of consumption of rice)
`implies24:18 : :60:x`
Product of means=Product of extremes
`implies24xx x=18xx60impliesx=(18xx60)/(24)=45kg`
`therefore` The consumption of rice for 18 days is 45 kg.
