Answer 1

Answer:

$\huge\large{\underbrace{\overbrace{\tt \red{Solution}}}}$

Cost price of an article ( c.p ) = Rs 200

loss ( l ) = 10%

reduction ( r ) = 5%

Selling price ( s.p )

$\longrightarrow$c.p[(100-l)/100][(100-r)/100]

$\longrightarrow$ 200[(100-10)/100][(100-5)/100]

$\longrightarrow$ 200×(90/100)(95/100)

$\longrightarrow$ ( 2 × 9 × 95 )/10

$\longrightarrow$ 9 × 19

${\implies{\boxed{\tt \red{ 171}}}}$

Therefore ,

Selling price of the article = Rs 171

Answer 2

$\huge\large{\underbrace{\overbrace{\tt \red{Solution}}}}$

Cost price of an article ( c.p ) = Rs 200

loss ( l ) = 10%

reduction ( r ) = 5%

Selling price ( s.p )

$\longrightarrow \: cp[(100-l)/100][(100-r)/100] \\ \longrightarrow 200[(100-10)/100][(100-5)/100]\\ \longrightarrow 200×(90/100)(95/100) \\ \longrightarrow ( 2 × 9 × 95 )/10 \\ \longrightarrow 9 × 19$${\implies{\boxed{\tt\red{ 171}}}}$

Therefore ,

Selling price of the article = Rs 171
