Question

A hostel of a school 168 students had food for 30 days. if 48 students leave the hostel. Find for many days will be the food last​

Answer 1

Answer:

42 days

Step-by-step explanation:

students days

168          30  

168-48    x

so,

students  days

168          30

 120        x

it's inverse variation as the number of students decrease, the number of days the food lasts increases.

x = 30*168/120

x = 42

(NOTE: incase you are facing difficulty in finding which direction to multiply, always see that it forms a L in any direction or 7.

like in this sum, 30 is multiplied with 168 and then divided by 120, so it forms a inverted L)
