• A. Rs 120.40
• B. Rs 220.40
• C. Rs 230.40
• D. none of these

Answer 1

The correct option is C Rs 230.40

List price of the machine=Rs320

after the first discount of 20% price will be$=320-\frac{20}{100}\times 320=256$

now a discount of 10% was given on Rs256

price of the machine will be,$=256-\frac{10}{100}\times 256=230.40$

The price he paid was Rs230.40
