An artist who needs to buy only paint and canvas finds that the cost of the canvas has decreased by 40 percent and the cost of paint has decreased by 60 percent. If paint previously accounted for 4 times as much of the expense of painting as did canvas, by what percent did the total cost for paint and canvas decrease?
A. 40%
B. 44%
C. 50%
D. 56%
E. 60%
The OA is D.
I solved this PS question as follows,
let canvas=10 and paint=40
total=50
new price will be
canvas=6 and paint=16
total=22
Decrease of 28
%= 28/50 *100=56.
Has anyone another strategic approach to solve this PS question? Regards!
