Question

Jack bought 9 dozens of earphones for R 2700.00. He sold a third of his stock and his income was R 1440.00. How many did he sell? How many are left?

Answer 1

Answer: 36 earphones are sold

Step-by-step explanation:

1 dozen = 12 pieces

so,

9 dozens = 12*9 = 108

now there are 108 numbers of earphones

and one third are sold

so,

1/3 of 108 = 36

so the answer is

36 earphones are sold
