Question

A shopkeeper sold a pen at a loss of 10%. If she h-
adsold it at Rs 14 more, she would have gained
25%. Find the cost price of the pen.
​

Answer 1

Answer:

Let take cost price = x ,

then by formula

S.P = ((100 - L%)/100)* C.P

S.P = (80/100)* x = (4/5) x

Now if he sell 200 more,

S.P = (4/5)x + 200

Profit will 5 %

S.P = ((100 + P% )/100) * C.P

=> (4/5)x + 200 = ((100 + 5)/100) * x

25x = 20000

x = 800

C.P is ₹ 800
