Given :- If you have enough food for 6 days for 8 people in your family. Then the material will last for how many days if 4 guests arrived at your house ?
Solution :-
we know that,
- M1 * D1 = M2 * D2 . { Here, M1 and M2 are numbers of people , and D1 and D2 are number of days.}
Let us assume that, the material will last for x days.
then,
M1 = 8 people
D1 = 6 days.
M2 = 8 + 4 = 12 people .
D2 = x days.
therefore,
→ M1 * D1 = M2 * D2
→ 8 * 6 = 12 * x
→ 48 = 12x
→ x = (48/12)
→ x = 4 days. (Ans.)
Hence, The material will last for 4 days.
