selling price is 16% it is the answer

Answer 2

Step-by-step explanation:

12:-S.P. of a chair =Rs.522

Profit=16%

∴C.P.=

100+Profit%

S.P.×100

=

100+16

522×100

=Rs.

116

522×100

=Rs.450

13:-S.P. of damaged garments =Rs.7360

Loss=8%

∴C.P.=

100−Loss%

S.P.×100

=

100−8

7360×100

=

92

7360×100

=Rs.8000

14:-Sp = 3168

loss= 12%

cp × loss= sp

cp(1-12/100)=3168

cp×88/100=3168

cp=28800/8

cp=72×50

cp=3600

now sp=3870

profit=3870-3600

=270

p%=270/3600 ×100

p%=30/4

p%=15/2

p%=7.5%
