Two pots are in side-by-side. One pot, which is 20 inches tall, casts a shadow that is 10
inches long. The other pot is 40 inches tall. Compute, in inches, the length of the shadow that
the taller pot casts. Choose the correct choice from the following choices
A) 25 B) 30 C) 10 D) 15 E) 20

Rationale: the ratio of shadow to height is constant , so if x is the length of the shadow , then 20 / 10 = 40 / x and x = 20 . correct answer e
Answer: E
