but I don't know how to solve it pls give breaf solution
it's a request ​

Answer 1

Answer:

S.P = 924

Gain % = 20

Loss % = 20

C.P=

100+20

100

​

×924=

120

100

​

×924=770

C.P with 20% Loss =

100−20

100

​

×924=

80

100

​

×924=1155

with CP of one article = 770

C.P of 2nd article = 1155

total CP = 770+1155= 1925

total S.P = 924×2=1848

total loss = 1925−1848

= 77 Rs

Step-by-step explanation:

Answer 2

Answer:

Loss=Rs 77

Step-by-step explanation:

let CP of the paintings is 100x and 100y

then SP1=100x+20x=120x=924

x=924/120

Sp2=100y-20y=80y=924

y=924/80

Total CP=100(x+y)

=100*(924/120+924/80)

=92400(120+80)/120*80

=924*200/96

CP=1925

SP=sp1+sp2=924*2=1848

Thus loss=1925-1848

=Rs 77
