Question

Ahmed buys a plot of land for rupees 480000. He sells 2/5 of it at a loss of 6%. At what gain per cent should he sell the the remaining part of the clot 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 %
