Answer 2

C.P. of the TV = ₹10,000

Profit% = 20%

As, we know
$sp \: = \frac{(100 + p\%)}{100} \times cp \\ = \frac{(100 + 20)}{100} \times 10000 \\ = \frac{120}{100} \times 10000 \\ = rs \: 12000$
Next Question :

SP of Washing Machine = ₹13,500

Loss% = 20%

As, we know
$cp = \frac{100}{(100 - l\%)} \times sp \\ = \frac{100}{(100 - 20)} \times 13500 \\ = \frac{100}{80} \times 13500 \\ = rs \: 16875$
Hope it Helps!
