In a student dormitory there was enough food to feed 300 students for 15 days, Became of admission of some new students the food only lasted for 10 days . How many new students are admitted to the dormitory? ans?
Answer is 150
I did it by assuming a value
Suppose each student eats 10 units of food per day
(300 i.e. students) (10 i.e. food consumed per day by a student) (15 i.e. total days the food was consumed ) = 45000
or we can wrire : 300x10x15 = 45000
Now a students are added and the rest of the values are constant
(300+ a) (10 ) (10i.e. the new value for total days the food was consumed) = 45000
or we can wrire : (300+ a) (10 ) (10) = 45000.................a = 150
