Question 260862
1st piece of land cost a and made profit of 0.15 a
2nd cost (120000 - a ) and made loss of (120000 - a) 0.1
Adding up 0.15a - 12000 + 0.1a = to a profit of 5500
Net cost is 0.25a - 12000 = 5500
So 0.25 a = 17,500
So a = 70000
Check 15% of 70 000 is 10,500 profit
10% 0f the rest (50000) is 5000 loss
Difference is $5500
