Question

Ahmed buys a plot of land for ₹480000.he sells 2/5 of it at a loss of 6% . At what gain per cent should he sells the remaining part of the plot to gain 10% on the whole

Answer 1

Buy of land =480000
 2/5*480000=192000 rs
loss=6%
100-6/100*192000=180480

total gain =10%
100+10/100*480000=528000

sp=528000-180480=347520

cp of remaining part of land =3/5*480000=288000

gain% of remaining part of land= sp-cp/cp*100

<=>347520-288000/288000*100
=20.6 %
