Question

Madumita is asked by her cousin to deliver a box containing 20 chocolates to her friend. Madumita is promised a reward of 10₨ for every chocolate she delivers but also a fine of 15₨ for every chocolate that she eats on her way. If she eats 5 chocolates on her way and delvers the rest, how much money will she receive from her cousin?

Answer 1

Answer:

75Rs

Step-by-step explanation:

This can be solved by turning the information in the prompt into two equations, 20 = E + D, and (10 x D) - (15 x E) = M. For this, E represents the number of chocolates Madumita ate along the way, D represents the number of chocolates she successfully delivered, and M represents how much money she will receive from her cousin: what we are looking for. Since they give us the number she ate along the way (E), we can plug that in to the first equation to find D.  ( 20 = 5 + D  ---->  15 = D ) Now that we have E and D, we can plug them into the second equation to find M.   (10 x 15) - (15 x 5) = M  -----> 150 - 75 = 75Rs.
