Dana purchased a bottle of persimmon syrup to make drinks. She used ³₅ of the syrup in February. She then used the remaining syrup in March and April in the ratio 1 : 6. Given that the amount of the persimmon syrup used in February was 0.95 ℓ more than that in March, how many millilitres of persimmon syrup did the bottle contain at first?

February	March	April	Total
3x7	2x7		5x7
	1x2	6x2
21 u	2 u	12 u	35 u

Total volume of March and April is combined repeated identity.  Make the total volume of March and April the same.  LCM of 2 and 7 is 14.

Volume of more persimmon syrup in the bottle used in February than March
= 21 u - 2 u
= 19 u

19 u = 0.95 

1 u = 0.95 ÷ 19 = 0.05

Amount of persimmon syrup in the bottle at first
= 35 u
= 35 x 0.05
= 1.75 ℓ

1 ℓ = 1000 mℓ

Amount of persimmon syrup in the bottle at first
= 1.75 x 1000
= 1750 mℓ

Answer(s): 1750 mℓ
