4%.Find the Cp. ​

Answer 1

Answer:

hope it helps

Step-by-step explanation:

s.p = Rs. 657.60

loss = 4%

c.p = ?

we know,

loss = (c.p - s.p ) ×100% ÷c.p

4 = (c.p - 657.60 ) ×100% ÷c.p

4 = 100c.p - 65760 ÷c.p

do cross multiply

4c.p = 100c.p - 65760

65760 = 100c.p - 4c.p

65760  = 96c.p

65760÷96 = c.p

658 = c.p

Therefore c.p = Rs 658
