Emily bought 20 mangosteens and 14 mangoes on Wednesday. Each day, she ate 3 mangosteens and 1 mango. She started eating her fruits on Thursday.

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

	Mangosteens	Mangoes
Before	20	14
Change	- 3 u	- 1 u
After	20 - 3 u	14 - 1 u

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

The number of mangoes and mangosteens in the end is equal.

20 - 3 u = 14 - 1 u
3 u - 1 u = 20 - 14
2 u = 6

1 u = 6 ÷ 2 = 3

Emily ate for 3 days from Thursday onwards.  At the end of Saturday, there would be an equal number of mangosteens and mangoes left.

(b)
Number of days from Thursday to Sunday = 4

Number of mangosteens left on Sunday
= 20 - (3 x 4)
= 20 - 12
= 8

Number of mangoes left on Sunday
= 14 - (1 x 4)
= 14 - 4
= 10

Number of mangoes more than mangosteens
= 10 - 8
= 2

Answer(s): (a) Saturday; (b) 2
