Question

find cp if so =rs 800 and loss% = 10%​

Answer 1

Step-by-step explanation:

Sp = rs 800

loss = 10%

Cp = ?

we know that,

cp= sp×100÷ 100-L%

= 800×100÷100-10

= 80000÷90

= 888.89#

Answer 2

Answer:

8000/9

Step-by-step explanation:

Loss%=CP-RS/CP*100%------------------------------------------- The formula

 Let's substitute

10/100=CP-800/CP

  Crisscross it

10*CP=100(CP-800)

10CP=100CP-80000

-90CP= -80000

CP=-80000/-90=           So the answer is 8000/9            

Notice that I understand "rs" as selling price
