Jane purchased a bottle of starfruit syrup to make drinks. She used ¹₄ of the syrup in March. She then used the remaining syrup in April and May in the ratio 2 : 9. Given that the amount of the starfruit syrup used in March was 0.2 ℓ more than that in April, how many millilitres of starfruit syrup did the bottle contain at first?

March	April	May	Total
1x11	3x11		4x11
	2x3	9x3
11 u	6 u	27 u	44 u

Total volume of April and May is combined repeated identity.  Make the total volume of April and May the same.  LCM of 3 and 11 is 33.

Volume of more starfruit syrup in the bottle used in March than April
= 11 u - 6 u
= 5 u

5 u = 0.2 

1 u = 0.2 ÷ 5 = 0.04

Amount of starfruit syrup in the bottle at first
= 44 u
= 44 x 0.04
= 1.76 ℓ

1 ℓ = 1000 mℓ

Amount of starfruit syrup in the bottle at first
= 1.76 x 1000
= 1760 mℓ

Answer(s): 1760 mℓ
