Question

Riya bought a TV set marked at Rs 30000. He got a discount of 10% and paid a sales tax of 7%. How much did riyaz pay for the TV set?

Answer 1

Riya paid Rs. 28,890 for the TV set.

Step-by-step explanation:

Marked price of TV set = M.P = Rs. 30000

Discount on a TV set = 10%

Price of the TV after discount =

$(1-\frac{10}{100})\times 30000\\= \frac{100 - 10}{100} \times 30000\\= \frac{90}{100}\times 30000\\= \frac{9}{10} \times 30000$

= 9 x 3000

= Rs. 27000

Sales tax = 7%

Price of TV after sales tax =

$(1+\frac{7}{100}}\times 27000\\= \frac{100+7}{100}\times 27000\\= \frac{107}{100}\times 27000$

= 107 x 270

= Rs. 28890

Hence, Riya paid Rs. 28,890 for the TV set.
