Question

A bakery owner procures burgers from a home baker. The cost price of 20 burgers is same as the selling price of x burgers. If the profit from selling burger is 25%, then the value of x is? *

Answer 1

${\huge{\underline{\large{\mathbb{\green{VERIFIED \: ANSWER}}}}}}$

Let the number of burgers sold in a week be 2x.

Hence, the number 'A" burgers sold is equal to the number of 'B' burgers sold which is in turn equal to x.

Now the profit for A will be 17x−450 and the profit for B will be 13x−310.

Assuming burger A's profit overtakes B's then 17x−450>13x−310 or 4x>140 or x>35.

Hence, after 35 burgers each, burger A profits will overtake burger B profits.
