Let us consider a total apples X.
Seller sells 40% of apples out of 100 apples (generally).
Remaining apples 420.
Then (100-40)%X = 420.
40%X = 420.
60/100*X = 420.
3/5X = 420;
X = 420*5/3;
X = 700.

@Nikky.
Hey, in your equation two unknowns are present. It is impossible to solve, you should know two values to solve that. Please check your equation once.

You wrote 46 instead of 36 yaar, that's why you got wrong answer.

In sum, we know after selling of 40%, 420 were left. so,
60% is 420 apples.
To know value of 1% : 420/60 = 7.
Now we got value of 1%, then 100% * 7 = 700.
Finally total apples are :700.

40%-------- X.
60%--------420.
X = 420*40/60.
= 280 .
= 280 + 420 = 700.
60%--------420.
X = 420*40/60.
= 280 .
= 280 + 420 = 700.

If we found the 40% of apple and the adding to the 60% we will get the 100%.
40% sold out.
Therefore remaining 60%=420.
For 60--420.
Then for 40--??
Therefore 40*420/60=280 .
Therefore 40% is 280.
We already have 60% i.e. 420.
420+280=700.
40% sold out.
Therefore remaining 60%=420.
For 60--420.
Then for 40--??
Therefore 40*420/60=280 .
Therefore 40% is 280.
We already have 60% i.e. 420.
420+280=700.

Short and simple.
Suppose total no.of oranges X.
So, % of oranges sold.
40% of x = 40X/100...........(1).
And given that 420 oranges are still remaining so,
The oranges sold = x-420 .......(2).
X*40/100= x-420.
From equation 1 & 2.
40X/100 = X-420.
40X= 100X-420,00.
420,00 = 60X.
X = 420,00/60.
X = 700 oranges.
Suppose total no.of oranges X.
So, % of oranges sold.
40% of x = 40X/100...........(1).
And given that 420 oranges are still remaining so,
The oranges sold = x-420 .......(2).
X*40/100= x-420.
From equation 1 & 2.
40X/100 = X-420.
40X= 100X-420,00.
420,00 = 60X.
X = 420,00/60.
X = 700 oranges.

Take total fruits as X.
Total fruits sold 40%.
Remaining is 60 ie 420 which is giver in the question,
Now 60%can be written as 60/100.
And,
60% of x which is total fruit can be written as 60/100*x.
Which is equal to 420.
So we can write,
60/100*x = 420.
We want total fruits means we want a value of x here,
x = 420*100/60.
= 42000/60.
= 4200/6.
x = 700.
Total fruits sold 40%.
Remaining is 60 ie 420 which is giver in the question,
Now 60%can be written as 60/100.
And,
60% of x which is total fruit can be written as 60/100*x.
Which is equal to 420.
So we can write,
60/100*x = 420.
We want total fruits means we want a value of x here,
x = 420*100/60.
= 42000/60.
= 4200/6.
x = 700.

Guys lets take Total Fruits % is 100.
We know remaining number of fruits = 420 ---> 60%.
? ---> 40%.
Simply do cross multiplication 60*? = 420*40.
? = (420*40)/60.
? = 280.
Total no.of Fruits 280+420 = 700.
We know remaining number of fruits = 420 ---> 60%.
? ---> 40%.
Simply do cross multiplication 60*? = 420*40.
? = (420*40)/60.
? = 280.
Total no.of Fruits 280+420 = 700.

He had 100% apples.
He sold 40%, Remaining 60% = 420 apples.
100% = 420/60*100 = 720.
He sold 40%, Remaining 60% = 420 apples.
100% = 420/60*100 = 720.
