Question

slove this problem and it's answer is 400

Answer 1

Here is your answer.......

Solution: Let marked price be Rs. x, Discount = 15%, Rate of Sales Tax = 10%. 

Discount on Rs. x = 15% of x = (15/100) x = 15x/100.

Price after discount = x – 15x/100 = 85x/100.

Sales Tax = 10% of 85x/100 = (10/100)(85x/100) = 85x/1000.

Price including sales tax = 85x/100 + 85x/1000 = 935x/1000.

As per question, 935x/1000 = Rs. 374

Or,    

x = Rs. 374(1000/935) = Rs. 400.

Hence,  marked price = Rs. 400. [Ans.]
