Question

A trader buys some orange at $50 each he finds that six of them are rotten. He sells the rest at $80 each and makes a profit of $450 how many oranges did he buy

Answer 1

Answer:

23

Step-by-step explanation:

let the total oranges bought be x

money spend = 50x

3 were rotten.

money earned=80(x-3)

so, 80x-240-50x=450

30x=690

x=23

Answer 2

Answer:

31

Step-by-step explanation:

let the number of oranges be X

after rotten number of oranges= X-6

each orange he buy = 50X

number of oranges he sold at= 80(X-6)

number of oranges he buy

80(X-6)-50X= 450

80X-480-50X=450

30X= 450+480

30X= 930

X= 31
