Marks: +1, -0

A, TV is sold at

8 \%

gain Had it been sold for ₹ 2553 less, there would have been loss of

15 \%

. To gain 18\%, the selling price (in ₹) of TV would be

13098
15000
9102
11100

Solution:

{CP}

of

{TV}=₹ x

Then,

{SP} \;\; = {CP} ×(\;{100+P \%}/{100})

\;\; =x ×(\;{100+8}/{100})=₹ \;{108 x}/{100}

According to the question,

\;\;{108 x}/{100}-2553=x ×(\;{100-15}/{100})

⇒\;\;{108 x}/{100}-2553=\;{85 x}/{100}

⇒\;\;{180 x}/{100}-\;{85 x}/{100}=2553

⇒\;x=\;{2553 × 100}/{23}=₹ 11100

∴

To gain

18 \%

, SP

=11100 ×(\;{100+18}/{100})

=111 × 118=₹ 13098
