Q.1 Total number of copy=250
He sells 25rs each copy =250×25=6250
30 copies are damaged,
remain copy= 250-30= 220 copies
he sells remain copy at the rate of 35rs
cost of remain copy = 220×35 =7700rs
profit= sp-cp
7700-6250= 450
profit%=profit×100/cp
450×100/6250 =6.4% Answer
Q.2 Selling price=1500
profit%=25%
cost price=?
Cp=Sp×100/(100+profit%) =
1500×100/100+25% = 1500×100/125
=1200rs Cost price Answer
