Question

A mug is sold for Rs. 288. If its cost price is numerically equal to twice the profit percentage, then what is the cost price?

Answer 1

Answer:

152

Explanation:

we know that ,

profit = selling price - cost price

given, cost price = 2.profit

let profit as p.

therefore, p = 288 - 2p

3p =288

p. =76.

hence cp = 2p

codt price = 2×76 = 152

Answer 2

The cost price is Rs. 160

Explanation:

As we know that

Profit percentage = (Selling price - cost price)  ÷ (Cost price) × 100

Let us assume the profit percentage be X

So, the cost price is 2X

Now placing the vales

X = (Rs. 288 - 2X) ÷ (2X) × 100

2X^2 = Rs 28,800 - 200 X

2X^2 + 200 X - 28,800 = 0

After solving this, the X value is 80

So, the cost price is

= 80 × 2

= Rs. 160
