Solution
Samir bought a shirt for Rs 336. This price includes 12% sales tax. Suppose printed price of shirt = Rs x. Then sales tax on shirt = 12% of x = 12/100 .x = 0.12x So price of shirt including sales tax = x+0.12x = 1.12 x So 1.12x = 336 x = 336/1.12 = Rs 300 Price of necktie including sales tax = Rs 110. Suppose printed price of necktie = Rs y Then sales tax on necktie = 10%of y = 10/100.y = 0.1y Price of necktie including sales tax = y+0.1y = 1.1y So 1.1 y = Rs 110 y = 110/1.1 = Rs 100
So printed price of shirt + necktie = Rs300+Rs100 = Rs400 Answer: Rs 400
