Question

If SP of 10 pens is equal to the CP of 14 pans find its gain or loss percent

Answer 1

Step-by-step explanation:

Let pens be x

now,the sp of pens =x/10

then,the cp of pens=x/14

Therefore,has gain= sp-cp

=x/10-x/14 (L.C.M=70)

=7x-5x/70

=2x/70

Profit or Gain =x/35

Gain% = P*100/CP

= x/35*100/x/14

= 14x*100/35x

= 1400x/35x

= 40

Gain% = 40% Ans.
