CP of the plot of land = ₹4,80,000
CP of th of the land =
Loss on th of the land = 6%
SP of th of the land = CP − Loss
CP of th of the land = 480000 − 192000 = ₹2,88,000
Total gain% = 10%
Total gain =
Total SP = CP + Gain = ₹4,80,000 + ₹48,000 = ₹5,28,000
SP of th of the land = ₹5,28,000 − ₹1,80,480 = ₹3,47,520
Gain on th of the land = SP of th land − CP of th land
= ₹3,47,520 − ₹2,88,000
= ₹59,520
Gain% on seling the remaining part of the plot =
