SolUtion
_______________________
Given :-
Marked price of T.V = Rs 18500
Two successive discounts are :-
20 %
5 %
Firstly we will find the single discount equivalent to 2 successive discounts
\bf{\underline{\mathcal{\pink{Formula}}}}
Formula
→
\begin{lgathered}(x + y - \frac{xy}{100} )\% \\\end{lgathered}
(x+y−
100
xy
)%
Here x refer to 1st discount and y refers to 2nd discount .
>> (20 + 5 - \frac{20 \times 5}{100} )\%>>(20+5−
100
20×5
)%
\begin{lgathered}>> (25 - \frac{100}{100} )\ \\\end{lgathered}
>>(25−
100
100
)
\begin{lgathered}>> (25 - 1) = 24\% \\\end{lgathered}
>>(25−1)=24%
Discount percentage = 24%

Discount →
\bf{\underline{\mathcal{\pink{Formula}}}}
Formula
\begin{lgathered}\frac{discount\% \times m.p}{100} \\\end{lgathered}
100
discount%×m.p
Discount = (24 × 18500)/100
Discount = 24 × 185
Discount = Rs 4,440
Now , Selling price = Marked price- Discount
→ 18500 - 4440
→ Rs 14,060
So the T.V is available at Rs 14,060
