Hi, Using the concept that Man×dayswork= constantSo here work is rupees spent, M1×d1w1=M2×d2w2Here M1= 12 and d1= 30 and w1= 1920 and M2=18 , w2=144012×301920=18×d21440d2=12×301920×144018=15 days

Solve this: Example 4. An army camp spends Rs 1920 as cost of wheat for 12 soldiers for 30 days. If they spend Rs 1440 for 18 soldiers, for how many days will the wheat last ?
