Vaidev, Dylan, Charlie and Ethan paid a total of $270 for a gift. Ethan paid ³₇ of what the rest paid. Vaidev paid 20% of what the rest paid. Dylan and Charlie paid an equal amount of money. How much did Charlie pay?

Vaidev	Dylan	Charlie	Ethan	Total
7x3			3x3	10x3
1x5	5x5			6x5
	1	1
5 u	8 u	8 u	9 u	30 u

20%= ²⁰₁₀₀= ¹₅
Vaidev's share : Total share = 1 : 5

The total amount paid for the gift is repeated.  Make the total amount the same.  LCM of 10 and 6 is 30.

Amount that Dylan, Charlie and Ethan paid = 25 u

Amount that Dylan and Charlie paid
= 25 u - 9 u
= 16 u

The amount that Dylan and Charlie each paid is the same.

Amount that Dylan and Charlie each paid
= 16 u ÷ 2
= 8 u

Cost of the gift = 30 u

30 u = 270

1 u = 270 ÷ 30 = 9

Amount that Charlie paid
= 8 u
= 8 x 9
= $72

Answer(s): $72
