Answer:
- 100 = 30 (four-leaf) + 70 (three-leaf);
- 200 = 60 (four-leaf) + 140 (three-leaf).
--------------------------------------
Every 3 clovers out of 10 have four leaves and the rest 7 have three leaves.
This gives us the ratio of clovers with four leaves by the total number:
If the total number is 100, then Lucy has:
- 100*3/10 = 30 four-leaf and 70 three-leaf clovers
If there are 200 clovers, then the number of four-leaf clovers is doubled:
- 30*2 = 60 and the number of three-leaf clovers is
