Question

find the C.P when S.P = rupees 405 anger loss percentage = 5 percentage ? please tell fast​

Answer 1

SP=RS40.

Loss percent=5, I.e.,Loss = 5%

Now,

let c.p.be Rs 100

As there is loss of 5, so,...

S.p=Rs 100-5=Rs95.

Again,

let the c.p be $'x'

Now, make the proportion as,

100/x =95/40.

cross multiply,

95x = 4000

x=4000/95

x=42.105

Hence, c.p=$42.105
