Question

A machine cost Rs 400. It is sold at a profit of 40%. What is the

selling price?​

Answer 1

Answer:

Let the cost price, C.P. be Rs. x

Profit =10%

Hence, S.P. =1.1(x)= Rs. 1.1x

If a loss has been incurred, then the selling price of the machine would be Rs. 0.9x.

Difference in selling prices =40

1.1x−0.9x=40

0.2x=40 or x=200

The cost price of the machine is Rs 200

hope it helps you

Answer 2

Answer:

S.P [Selling Price ] of The machine = ₹ 560

Explanation

Given

• C. P of machine = ₹ 400

• Profit % = 40

To Find

• S. P [Selling Price ]

Solution

• We know that to find S. P when C. P and Profit % is given we use the formula :-

• $\boxed { \sf{ S. P = \dfrac{100+profit \%} {100} \times C. P}}$

• $\boxed { \sf{ S. P = \dfrac{100+40} {100} \times 400}}$

• $\sf {S.P = \dfrac{140}{100} \times 400}$

• $\sf {S.P = \dfrac{140}{1\cancel0\cancel0} \times 4\cancel0\cancel0}$

• S. P = 140 × 4

• S.P =₹ 560
