Question

Ramu sold a plot of land for 240000 gaining 20% .For how much did he purchase the plot

Answer 1

SP=240000
Gain=20%
Let CP=x
:.Eqⁿ
X+20%ofx=240000
X+20/×x=240000
x/x+20/100x=240000
120x/=240000
X=240000×100/120
X=240000×10/12
X=20000×10
CP=200000

Answer 2

Answer:

sp=2,00,000

cp=x

gain Percentage=20% on

gain =

$\frac{20}{100} \times x = \frac{20x}{100}$

=gain + cp

$\frac{x + 20}{100}$

$= \frac{100x + 20x }{100}$

$= \frac{120x}{100}$

selling price =cost price+gain

$240000 = \frac{120x}{100}$

$= 120x = 240000 \times 100 \\ x = \frac{240000 \times 100}{120} \\ x = 20000$

c.p=20000
