How many in the crate

Question

A crate of oranges was shared equally among 15 people. 5 people gave up 3 fifths of their share. As a result, the remaining people received 12 more oranges each. How many oranges were there in the crate at first

 

Answer 1

N/15

 

12*12 = 5(3/5)(n/15) = n/5

 

144 = n/5

 

n = 720

 

720 oranges divided by 15 people = 48 oranges per person

 

5 people gave of 3/5 of 48 = 5 x 3/5 x 48 = 3x48 = 144 = 12 x 12

 

720 oranges
