Question

Reena bought two tables for Rs. 1800 each he sold one at a loss of 8% and the other at a profit of 12% find the selling price of each also find out the total profit or loss

Answer 1

$cp = 1800 \\ p.\% = 12\% \\ l.\% = 8\% \\ \\ sp = 100(p) \div 100 \times cp \\ = 100(12) \div 100 \times 1800 \\ = 120 \div 100 \times 1800 \\ = 120 \times 18 \\ = 2160 \\ \\ p\% =sp \div p \times 100 \\ = 30 \times 100 \\ = 3000$
there fore find profit and sp

Answer 2

cp=1800

p.%=12%

l.%=8%

sp=100(p)÷100×cp

=100(12)÷100×1800

=120÷100×1800

=120×18

=2160

p%=sp÷p×100

=30×100

=3000

there fore find profit and sp
