• A. $143:144$
• B. $19:11$
• C. $136:135$
• D. $73:77$

Answer 1

The correct option is C $136:135$

Let the selling price of the cold drink is Rs. $100$

Pepsi gives two successive discount $10\%$ and $25\%$

Then selling price after first discount:

S.P $=100-100\times \frac{10}{100}$

S.P $=100-10=$ Rs. $90$

Selling price after second discount:

S.P $=90-90\times \frac{25}{100}$

S.P $=90-22.5=$ Rs. $67.5$

Coke gives two successive discount $15\%$ and $20\%$.

Then selling price after first discount

S.P $=100-100\times \frac{15}{100}$

S.P $=100-15=$ Rs. $85$

Selling price after second discount:

S.P $=85-85\times \frac{20}{100}$

$S.P=85-17=$Rs. $68$

Ratio of the S.P$=68:67.5$

$=680:675$

$=136:135$
