Answer 1

Cost price of tv is = 21000

After one year value decreased by 5%

So ATQ

Current value = C.P -5%of C.P

=21000 -5/100×21000

=19950

Answer 2

Answer:

${ \huge \bf{ \mid{ \overline{ \underline{\red {A\green n\purple s\pink wer}}}} \mid}}$

$\small\underline\textsf{\red{ the value of TV after one Year}=\underline{19,950}}$

$\small\underline\frak{Given}$

$\sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: pricipal = rs.21000 \\\sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:reduction = 5\% \: of \: 21000 \: per \: year$

$\small\star\underline\frak{to \:find :- }$

$\small\underline\textsf{the value of TV after one Year}$

$\huge\underline\textsf{Explantion:-}$

$\boxed{\boxed{\underline{\sf{\frac{21000 \times 5 \times 1}{100} = 1050}}}}$

$\sf value \: at \: the \: end \: of \: 1 \: year \\\sf \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:= 21000 - 1050 = 19,950$

$\rule{300}{2}$

$\huge\underline\frak{Alternately:- }$

$\small\underline\textsf{we \: may \: directly \: get \: this \: as \: follows}$

$\sf value \: at \: the \: end \: of \: 1 \: year = \boxed{(1 - \frac{5}{100})}$

$\boxed{\boxed{\boxed{\sf 21000 \times \frac{19}{20}}}}$

$\star\sf 19,950$
