Can we do like this?
40%x+420=x
(40/100)x+420=x
420=x-(2/5)x
2100=3x
x=700.
40%x+420=x
(40/100)x+420=x
420=x-(2/5)x
2100=3x
x=700.

420/x * 100 = 60,
420/x = 3/5,
420.5 = 3.x,
2100 = 3.x,
2100/3 = x,
700 = x.
420/x = 3/5,
420.5 = 3.x,
2100 = 3.x,
2100/3 = x,
700 = x.

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

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

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.

Remaining 60 percent = 420.
So, 20 percent = 14.
So, 100 percent = 700.
So, 20 percent = 14.
So, 100 percent = 700.

He had X apples.
So,
X-40/100(40%)=420.
X=700 this method is so simple.

X-40/100(40%)=420.

45/100*x=30/100*90=30/100*210
9x/20+27=63
9x/20=63-27
x=(36*20)/9
x=80
9x/20+27=63
9x/20=63-27
x=(36*20)/9
x=80
