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:
8000/9
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
