पर्याय

• I

• II

• III

• IV

Answer 1

IV
Explanation :

I. Equivalent single discount to 10% and 10%

= `10+10-(10xx10)/100` = 19%

II. Equivalent single discount to 12% and 8%

 = `12+8-(12xx8)/100`

= 20 - 0.96%

= 19.04%

III. Equivalent single discount to 15% and 5%

= `15+5-(15xx5)/100`

= 20 - 0.75

 = 19.25%

IV. Equivalent single discount to 20% = 20%

So, the selling price will be minimum under scheme IV as in this scheme, the discount is maximum.
