The figure above shows a path around a triangular piece of land. Mary walked the distance of 8 miles from P to Q and then walked the distance of 6 miles from Q to R. If Ted walked directly from P to R, by what percent did the distance that Mary walked exceed the distance that Ted walked?

(A) 30%

(B) 40%

(C) 50%

(D) 60%

(E) 80%

Kudos for a correct solution.Attachment:

The standard measurement of 90 degree scale is 3-4-5

So, if we multiply the measurement by 2 then I’ll get it as 6-8-10.

That means, PQ=10,

So, Ted’s walk distance is 10.

Distance walked by Mary = 8+6 = 14.

So Mary walked 4 miles more than Ted. If I want to make 100% of Mary’s walk, I have to multiply it by 10. Simultaneously, Ted’s walk will be 4*10=40%.

So the answer is (B)
