A ) 66.67%

30(x+y) - 30x = 20x

y = 20x/30

y = 0.6667

Let x be cost of 20 articles

each would cost x/20

profit % = profit/CP*100

since profit of 30 = CP of 20 = x

30 CP is 30x/20

Numerator = x

Denominator = 30x/20

So profit% = n/d * 100

=2/3*100 = 66.67

OA is C ( or B) not A. Can anybody explain?

30(S-C)=20C
S=5C/3,
%profit=S-C=5C/3-C=0.666 C=66.67%C
