A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
statuscvo [17]

Answer:

Cost price of the fan is \text {Rs. 470.59}.

Step-by-step explanation:

Given: A man sold a fan for  \text{Rs.}\:400. He incurred a loss of 15\%.

To find: The cost price of the fan

Solution:

We have,

Selling price, S.P.,  of the fan = \text{Rs.} 400

Loss =15\%

We know that \text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%

Now let the C.P. of the fan be \text{Rs.} \:x

So, 15=(\frac{x-400}{x})\times 100

\implies 15x=100x-40000

\implies 100x-15x=40000

\implies 85x=40000

\implies x=\frac{40000}{85}

\implies x= 470.59

Hence, the cost price of the fan is \text {Rs. 470.59}.

coldgirl [10]

Answer:

8

Step-by-step explanation:

The numbers are 6 and 2x, then:

  • 1/6 + 1/(2x) = 7/24
  • 1/3 + 1/x = 7/12
  • (x+3)/(3x) = 7/12
  • 12(x+3) = 7*3x
  • 12x + 36 = 21x
  • 21x - 12x = 36
  • 9x = 36
  • x = 4

The other number is 2*4 = 8
