Answer 1

Step-by-step explanation:

given

cp= 15×30=450

sp= 525

profit=sp-cp

=525 - 450

=75

profit %age= 75/450×100

=75/4.5=16.67

cp=900

sp=972

profit=sp-cp=972-900= 72

profit%age=profit/cp×100

=72/900×100=72/9=8

cp=2,50,000

total cp = 2,50,000 + 50,000=3, 00,000

sp=4, 00,000

profit=4, 00,000-3, 00,000=1, 00,000

profit%age=1, 00,000/300000×100=100000/3000=33.33
