Karthik distributed 10 acres of land to Ganesh and Ravindra who paid him the total amount in the ratio of 2:3. Ganesh invested further Rs. 2 lakhs in the land and planted coconut and lemon trees in the ratio of 5: 1 on equal areas of land. There was a total of 100 lemon trees. The cost of one coconut was Rs. 5. The crop took 7 years to mature and when the crop was reaped in 2019, the total revenue generated was 25% of the total amount put in by Ganesh and Ravindra together. The revenue generated from the coconut and lemon trees was in the ratio of 3: 2 and it was shared equally by Ganesh and Ravindra as the initial amount spent by them were equal. 

What was the ratio of yields per acre of land for coconuts and lemons (in terms of the number of lemons and coconuts)?
