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.

Remaining apple = 60%.

60% = 420.

100% = ?

So, (100*420)/60 = 700.

He had 100% apples.

He sold 40%, Remaining 60% = 420 apples.

100% = 420/60*100 = 720.

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.

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.

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.

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%-------- X.
60%--------420.

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

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.

@Aparna.

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

@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.
