Question

ball point pen were sold at loss of 20% if they were sold at rs 70 more therr would be a gain of 10/3% what is total cost Price??

Answer 1

Let the cost price of the pen be X.
20% of X = (20/100)*X=X/5
Selling at 20% loss = X-X/5=4X/5
Selling for 70 more gives profit of 10/3%
Profit %=(profit/C.P)*100
And profit = S.P-C.P=(4X/5 + 70) - X
= 70 - X/5
Therefore 10/3 = {(70- X/5)/X}*100
On solving for X, we get X=300.
Hence the answer is 300
