Question

some articles were bought at 6 articles for Rs5 and sold at 5articles for Rs6.gain percent is

Answer 1

Cost of 1 article = Rs 5/6.
selling price of 1 article = Rs 6/5.
profit = 6/5 - 5/6 = Rs 11/30.
% gain = (11/30)/5/6*100 = 11/25 = 44%

Answer 2

C.p of 6 article = Rs.5
C.p of 1 article =5/6

S.p of 5 articles = Rs.6
S.p of 1 article = 6/5

C.p ( ) S.p
5/6 ( ) 6/5
Now we have to do cross multiplication.
So it is 5×5 ( ) 6 × 6
25 (<) 36
S.p is greater than c.p
So it is a profit.
Profit = s.p - c.p
= 6/5 -5/6
=36-25/30
=11/30
Gain % = 11×6/30×5 × 100
= 220/5
= 44%
So, the gain percent is 44%
