Victoria purchased a bottle of mango syrup to make drinks. She used ³₅ of the syrup in January. She then used the remaining syrup in February and March in the ratio 4 : 5. Given that the amount of the mango syrup used in January was 0.95 ℓ more than that in February, how many millilitres of mango syrup did the bottle contain at first?

January	February	March	Total
3x9	2x9		5x9
	4x2	5x2
27 u	8 u	10 u	45 u

Total volume of February and March is combined repeated identity.  Make the total volume of February and March the same.  LCM of 2 and 9 is 18.

Volume of more mango syrup in the bottle used in January than February
= 27 u - 8 u
= 19 u

19 u = 0.95 

1 u = 0.95 ÷ 19 = 0.05

Amount of mango syrup in the bottle at first
= 45 u
= 45 x 0.05
= 2.25 ℓ

1 ℓ = 1000 mℓ

Amount of mango syrup in the bottle at first
= 2.25 x 1000
= 2250 mℓ

Answer(s): 2250 mℓ
