Find the sp cp = 640 profit % = 40 %​

Answer 1

Answer:

• Selling Price is 896 rupees.

step by step explanation:

Given:

• Cp = 640 rupees
• Profit % = 40 %

To Find:

• Find SP =?

According to the question,Cost Price is given here and profit % is also given here so here said to find selling price.

We know that,

$\rm{S.P = \dfrac{100 + Gain\%}{100}\times C.P}$

Now,putting on formula

$\: \: \sf \implies \: s.p = 640(1 + \frac{40}{100} ) \\ \\ \: \: \sf \implies \: s.p = 640( \frac{100 + 40}{100} ) \\ \\ \: \: \sf \implies \: s.p = 640 (\frac{14 \cancel0}{10 \cancel0} ) \\ \\ \: \: \sf \implies \: s.p = 64 \cancel0 \times \frac{14} { 1 \cancel0} \\ \\ \: \: \sf \implies \: s.p = 64 \times 14 \\ \\ \: \: \sf \implies \: s.p = 896 \: rupees$

Therefore, Selling Price is 896 rupees.
