Answer 1

$\large\boxed{\sf{†Solution†}}$

C.P of article:

$\sf{\small1140 \times \large\frac{100}{95} = \small rs.1120}$

S.P at 5% gain:

$\sf{\large \frac{1200 \times 105}{100} =\small rs.1260 }$

Using Rule 3,

$\sf{C.P = S.P\large( \frac{100}{100 - loss\%}) }$

$\sf{1140\large( \frac{100}{100 - 5}) = \frac{114000}{95} }$

$\sf{=rs \: 1200}$

$\sf{S.P = C.P \times \large( \frac{100 + profit\%}{100} )}$

$\sf{=1200\large( \frac{100 + 5}{100}) }$

$\sf{=1200\large \times \frac{105}{100} }$

$\sf{=rs.1260}$

Hence, the article should be sold at rs.1260 in order to gain the 5% .
