Question

If $40$ persons consume $240$ kg of rice in $15$ days. In how many days will 30 persons consume $48$ kg of rice?

• A. $2$ days
• B. $3$ days
• C. $4$ days
• D. $5$days

Answer 1

The correct option is C $4$ days

$\because$ 40 persons in 15 day consumes 240 kg

$\therefore$ 1 persons in 15 day will consume $=\frac{240}{40}=6$ kg

$\therefore$ 1 persons in 1 day will consume $=\frac{6}{15}=0.4$ kg

$\therefore$ 30 persons in 1 day will consume $=0.4\times 30=12$ kg

Time taken to consume 48 kg $=\frac{48}{12}=4$ days

option C is the correct answer.
