Question

In a camp of 180 students had ration for 20 days. How many students should leave the camp if the ration should last for 25 days

Answer 1

Answer:

36

Step-by-step explanation:

Total Ration = x

Consumption of Each student for 20 days = x / 180

Consumption of Each student for Per day = x / (180 x 20)

∴ Consumption of Each student for Per day = x / 3600

Now we want ration to continue for 25 days.

Total of number of students be y for 25 days consumption.

x / 3600 * y * 25 = x

y = 3600 / 25= 144

So total number of students to leave = 180 - 144 = 36

Answer 2

Step-by-step explanation:

Food for 180 students for 20 days = x students for 25 days

ratio = 180 × 20 = x × 25

Then x = 180×20/25 = 144

144 students had food for 25 days

Then 180 -144 = 36 student leave the camp

36 students leave the camp ÃŇŠWƏŘ
