Kylie, Jade, Fanny and Min jointly contributed to the cost of a present for their colleague. Kylie's contribution is ⁴₇ of the total contribution made by the four girls. The ratio of Min's contribution to the total of Jade's and Fanny's contribution is 5 : 2. What is the total contribution by the four girls if Jade's contribution is ²₇ of Fanny's contribution and the total amount contributed by Kylie and Min is $2064?

Kylie	Jade	Fanny	Min	Total
4x21	3x21			7x21
	2x9		5x9
	2x2	7x2
84 u	4 u	14 u	45 u	147 u

Working backwards.

Total amount that Jade and Fanny had is the combined repeated identity.
LCM of 2 and 9 = 18

Total amount that Jade, Fanny and Min had is the next combined repeated identity.
LCM of 3 and 21 = 63 

Total amount contributed by Kylie and Min
= 84 u + 45 u
= 129 u

129 u = 2064

2 u = 2064 ÷ 129 = $16

Total contribution by the four girls
= 147 u
= 147 x 16
= $2352

Answer(s): $2352
