Answer 1

Answer:

(i) cost price 24

selling price 30

profit (30-24)=6

profit percent =profit×100/cost price

=6×100/24%=25%

(ii) cost price=250

selling price =200

loss=250-200=50

loss percent =50×100/250%=20%

(iii) cost price =300

selling price =360

profit=360-300=60

profit percent =60×100/300%=20%

(iv) cost price=1800

selling price=1600

loss=1800-1600=200

loss percent =200×100/1800%=100/9%=11 1/9%
