Question

Amal sells 2 laptop for Rs.19550 each gaining 15% on one and losing 15% on the other. Find her gain or loss % in the whole transaction​

Answer 1

Answer:

2.25 % Loss

Step-by-step explanation:

1st method :

when ,

SP (1) = SP (2)

+R %. = - R %

{Always loss }

loss % = R^2/ 100

loss % = 225/100

loss % = 2.25 %

2nd method :

CP SP

1ST {20 : 23} × 17

2ND {20 : 17 } × 23

S.P of both the laptop are same.

TOTAL CP = 340 + 460 = 800

TOTAL SP = 391 + 391 = 782

Loss = 800 - 782 = 18

% = 18×100/800

% = 2.25 % Loss

Answer 2

hence loss percentage= 2.25%
