Question

The differences in prices when a commodity is sold at a profit of 4% and at a profit of 6%is Rs.3.find the selling prices of commodity in two cases??????????????

Answer 1

Let SP = Rs x

itz Sp at profit of 4% =Rs( x . 104/100)
=Rs 104x/100

itz sp at profit of 6% = Rs( x . 106/100)
=Rs106x/100

difference in between selling price= Rs 3

106x/100 - 104x/100 = Rs 3

after cross multiplication

106x - 104x = Rs 3 . 100

2x = Rs300

x = Rs 300/2

x = Rs 150

mns sp = 150 rs

Answer 2

Let the cp be 100

So sp at 4%gain=104

Sp at 6% gain=106

Difference =3

So 106-104=3rs

2=3rs

So 1=3/2

And 100=3/2*100=150

Cp=150

Sp at 4%=150+4/100*150=6

Sp at 4%=156

Sp at 6%=150+6/100*150=9

Sp at 6%=159
