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

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.
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.
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.
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.
40% of x = 0.4x.
x - 0.4x = 420.
x(1-0.4) = 420.
x = 420/0.6.
x = 700.
