Question

A fruit seller had some apples. he sells 40% of them and still has 420 apples. find the number of apples he had originally.​

Answer 1

Answer:

700

Step-by-step explanation:

Let the total no.of apples he had originally be x.

x - 420 = 40% of x

x - 420 = 40x/100

(x - 420)/1 = 2x/5

2x(1) = 5(x-420)

2x = 5x - 2100

2100 = 5x-2x

2100 = 3x

x=2100/3

x=700

Thus, the total no.of apples he had originally are 700

Answer 2

100 - 40 = 60% of x = 420.
60/100 x = 420.
Therefore, 2/5 th of x is 420.
Hence x (total) = 420 *5/ 2 = 2100/2 = 1050.
