• A. Rs. 100
• B. Rs. 150
• C. Rs. 200
• D. Rs. 500

Answer 1

The correct option is C Rs. 200

Let original C.P. be Rs. x
$S.P.=\frac{105}{100}x=\frac{21x}{20}NewC.P.=\frac{95}{100}x=\frac{19x}{20}NewS.P.=\frac{110}{100}\times \frac{19x}{20}=\frac{209x}{200}\frac{21x}{20}-\frac{209x}{200}=1orx=200$
