Question

sp =rs 540. profit %= 20% cp = ?

Answer 1

Hey mate!

Sp = rs. 540

profit % = 20

= 20/100 x 540 = 108rs

so, C.P = S.P - profit

= 540 - 108

= 432rs.

Cost price = 432rs.

Thanks!

$<b>Your Answer :-$

Given :-

SP = ₹540
Profit % = 20
CP = ?

We can solve the problem by using the formula given below :-

$cp = sp( \frac{100}{100 + gain\%} )$

So the Solution is :-

$cp = rs \: 540( \frac{100}{100 + 20} ) \\ cp = rs \: 540( \frac{100}{120} ) \\ cp = rs \: 540 \times \frac{5}{6 } \\ cp = rs \: 90 \times 5 \\ cp = rs \: 450$

Hence, the cost price is ₹450.
