Question 23
Mrs. X spends Rs. 535 in purchasing some shirts and ties for her husband. If shirts cost Rs. 43 each and the ties cost Rs.21 each, then what is the ratio of the shirts to the ties, that are purchased ?
Solution
Given,
Cost of each shirt = Rs. 43
Cost of each tie = Rs. 21
Let x, y be the number of shirts and ties purchased
x*43+ y*21 = 535
y = $$\ \frac{\ 535-43x}{21}$$
when x = 10, y is an integer i.e y =5
ratio of shirts to ties purchased = 10:5 =2:1
B is the correct answer.
