Question

Geeta made a profit of 25% on cost price by selling an article. How much it presents on selling price?​

Answer 1

Answer:

we first take out the cost of eggs per 100

let x be the cost of eggs per 100. then,

8.40/12 = x/100  <direct proportion>

=  8.40×100 = 12x

=  840/12 = x

= 70 = x

the cost of eggs per 100 is Rs70.

15% of 70 = 15/100×70 = 10.5

70+10.5 = 80.5

Geeta must sell the eggs at the cost of Rs80.50 per hundred to earn a profit of 15 percent.
