3) 10
4) 12
5) 18​

Answer 1

Answer:

4) 12

Explanation:

JACK

Jack bought the laptop at RS X.

Therefore RS. X = 100%

lets calculate the % profit after selling

40/100 x RS X. = RS 40/100X.

Assume. RS. X = 100

PROFIT = 40/100 Multiplied by 100

             =RS. 40

JILL

Jill bought the laptop at RS X. + RS. 40 ( Jack's profit)

Assume RS. X. to be RS. 100

• Therefore Jill bought the laptop at RS. 140.

RS. 140 becomes our 100%

Jill then sold the laptop at a loss of 20%

If RS. 140 = 100%

Lets find 20% of RS. 140

20/100 * RS 140 = RS. 28.

RS. 28 is the loss he sold the laptop.

• Therefore Jill sold the laptop at RS. 140 - RS. 28

      = RS. 112.

So if Jill had bought the Laptop directly from Pheonix Digital he would have made a profit of 12.

Having asumed RS.X to be 100

• Therefore RS. 112 - RS. 100

       = RS. 12

PERCENTAGE PROFIT

RS. 100 = 100%

RS. 12 = ?

12/100 *100 =12

=12%.
