Question

23. An article is sold at a profit of 20%. If both the cost price and selling price are Rs 100 less, the profit would be 4% more. Find the cost price.
(a) 600
(b) 500
(c) 400
(d) 800​

Answer 1

Answer:

a)600

Step-by-step explanation:

Let CP X.

SP = 1.2X.

When CP is Rs. 100 less,

CP = X - 100

SP = 1.2X - 100.

Now,

1.2X - 100 = 1.24*(X-100)

On Solving, we get

X = 600.

CP = Rs. 600.
