A fruit seller had some apples. He sells 40% apples and still has 420 apples. Originally, he had:
588 apples
600 apples
672 apples
700 apples
Answer: Option
Explanation:

Suppose originally he had x apples.

Then, (100 - 40)% of x = 420.

60 x x = 420
100

x = 420 x 100   = 700.
60

There are so many process but we need only short one.
100-40= 60%
60%= 420
100% = 420*100/60
=700

x=40/100[x+420]
10x=4x+1680
6x=1680
x=1680/6
x=280
So the original apple=x+420

=280+420
=700

100-40=60%

60%=420

So 100%= 420*100*100/100*60=700

Its more short type.

It is very simple.

If 40% is sold out then 60% is remains.

Then,

(420/60) *100= 700.

It really simple .

See if 40% sold out then remain is 60%,
That means 60% = 420.

Let total number of fruit is X, we have to find the value Of X?

So, 60/100*X = 420 as of question,
X = 4200/6 = 700(ans).

Person sold 40% of apples. Then 60% of apples are leftover.

420 = 60%

He asked to find out total number of apples, and total number of apples are given in the options.

That means take the options individually and find 60% of that number, if the answer is 420, then thats the total number of appeals he had.

I hope this is the best answer:

Consider x = Original number of apples, Sold 40% of x
remaining is 420.

x-40% of x = 420.

x-40/100 x = 420.

x-2x/5 = 420 (dividing 40/100 =2/5).

x = 700.

Short one:

Remaining apples (100%-40%) = 60%.

60% = 420.

40% = (40*420) /60.

= 280 (unitary method).

Answer = 280+420.

= 700.

40/100*x+420 = x.

40x+42000 = 100x.

42000 = 60x.

700 = x.

Let the no.of the apples be x.

40% of x = 0.4x.

x - 0.4x = 420.

x(1-0.4) = 420.

x = 420/0.6.

x = 700.
