А The marked price of a mobile is 25% above its cost price, When it is sold at a gain of
10%, the profit amounts to Rs 725. Find the marked price of the mobile.

The marked price is Rs 823.86

Step-by-step explanation:

Let the cost price be Rs x. The marked price of the mobile is 25% above its cost price. Therefore:

The marked price = x + 25%(x) = 1 + 0.25x = 1.25x

When the mobile phone is sold at a gain of 10%. the profit is Rs 725, to find the cost price we use:

x + 10%(x) = 725

x + 0.1(x) = 725

1.1x = 725

x = 725/1.1 = 659.09

The cost price is Rs 659.09. Therefore the marked price is given as:

Marked price  = 1.25x = 1.25(659.09) = 823.86

The marked price is Rs 823.86

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
