Answer 2

Answer: Janice is 1 inch taller than Krysta.

Explanation:

Let the height of Krysta denoted by h .

According to the given statements , we will write height of each person in terms of 'h'.

Kathleen is 6 inches shorter than Krysta.

i.e. Height of Kathleen = h-6

Evan is 13 inches taller than Kathleen.

i.e. Height of Evan = (h-6)+13=h-6+13=h+7

i.e. Height of Evan =h+7

David is 2 inches shorter than Evan.

i.e. Height of David = (h+7)-2 =h+7-2

Height of David =h+5

Janice is 4 inches shorter than David.

i.e. Height of Janice= (h+5)-4=h+1

i.e. height of Janice = height of Krysta+ 1 inch [∵ h= height of Krysta]

⇒ Janice is 1 inch taller than Krysta.
