Question

Mr.Johnson imported some cartons of noodles.There were 28 packages of in each carton.he then sold 10 of noodles for $5 if he received $280 from the sale of noodles.How many cartons of noodles did he sell?

Answer 1

The total number of cartons did he sale is 20 .

Explanation:

Given as :

The total number package in each carton = 28

The total amount received after sale = $ 280

The cost of 10 noodles = $ 5

Let the total number of cartoon sale = x

According to question

∵ The number of noodles costing $5 is 10

so,The number of noodles costing $1 is
`(10)/(5)` = 2

∴ The number of noodles costing $280 = 2 × 280 = 560

Now, since there are 28 packages in 1 carton

So . the number of carton did he sale =
`(\textrm total number of noodles)/(\textrm total package in each cartoon)`

Or, The number of carton did he sale =
`(560)/(28)` = 20

Hence The total number of cartons did he sale is 20 . Answer
