Question

An article was sold in ₹ 250 at a profit of 5%. What was cost price

Answer 1

S. P=250 rs
Profit%=5%
Let the C.p. Be 'x'
x+x*5/100=250
105x/100=250
21x/20=250
x=250*20/21
x=5000/21
x=238(approx)

Answer 2

let sp=100 percent
it includes 5./.of profit hence if we remove profit we get cp
so let 250=100./.
10./.=25
5./.=12.5

removal of 12.5 to get cp: cp= sp - profit ./.
250-12.5=238.5
