Diana bought 25 oranges and 13 pomegranates on Friday. Each day, she ate 5 oranges and 1 pomegranate. She started eating her fruits on Saturday.

1. At the end of which day would there be an equal number of oranges and pomegranates left? Give your answer in the following format. (Eg Monday)
2. How many more pomegranates than oranges were there on Tuesday?

	Oranges	Pomegranates
Before	25	13
Change	- 5 u	- 1 u
After	25 - 5 u	13 - 1 u

(a)
Let the number of days be 1 u.

The number of pomegranates and oranges in the end is equal.

25 - 5 u = 13 - 1 u
5 u - 1 u = 25 - 13
4 u = 12

1 u = 12 ÷ 4 = 3

Diana ate for 3 days from Saturday onwards.  At the end of Monday, there would be an equal number of oranges and pomegranates left.

(b)
Number of days from Saturday to Tuesday = 4

Number of oranges left on Tuesday
= 25 - (5 x 4)
= 25 - 20
= 5

Number of pomegranates left on Tuesday
= 13 - (1 x 4)
= 13 - 4
= 9

Number of pomegranates more than oranges
= 9 - 5
= 4

Answer(s): (a) Monday; (b) 4
