Comparing Linda and
Usha in the end |
5 p |
3 p |
2 p |
Volume of tea that Linda had in the end
= 1 u + 1560 - 480
= 1 u + 1080
Difference in the volume of tea between Linda and Usha in the end
= 5 p - 3 p
= 2 p
2 p = 1080 - 480
2 p = 600
1 p = 600 ÷ 2 = 300
Volume of tea that Linda had at first
= 5 p + 480
= 5 x 300 + 480
= 1500 + 480
= 1980 mℓ
Answer(s): 1980 mℓ
