A reduction of 15% in the price of a shirt resulted in the reduction of the price of the shirt by Tk 21. What was the previous price of the shirt?
A
Tk. 175
B
Tk. 140
C
Tk. 150
D
Tk. 120
Correct Answer: Tk. 140
Let the previous price of the shirt be x.According to the problem, the price of the shirt was reduced by 15%, which can be written mathematically as:x - 0.15x = 0.85xAlso, it is given that the reduction in the price of the shirt was Tk 21. So we can write:0.85x = x - 21Simplifying this equation, we get:0.15x = 21Dividing both sides by 0.15, we get:x = 140Therefore, the previous price of the shirt was Tk 140
