Total price of a shirt and a pant is Tk. 850. If the price of the shirt increases by 12% and the pant by 5% then the total price become Tk. 934.50. What was the original price of the shirt before price increment?
A
Tk. 620
B
Tk. 650
C
Tk. 675
D
Tk. 600
Correct Answer: Tk. 600
Let the original prices of the shirt and the pant be S & P respectively. Then, S + P = 850 or, P = 850 - S Again, 1.12S + 1.05P = 934.50 or, 1.12S + 1.05(850 - S) = 934.50 or, 1.12S + 1.05x850 - 1.05S = 934.50 or, 0.07S = 934.50 - 892.50 = 42 or, S = 42/0.07 = 600 TK.
