Answer 1

Answer:

hey buddy

Step-by-step explanation:

Let Bar choco cost 10 Rs so from ques. Bar Milk is 14 Rs and the total cost of bablu order is (14x+10y) here x and y are no.of pieces of bar choco and Bar milk.

By mistake no. are swapped so now cost will be (14y+10x) and it was less than 10% so,

14x + 10y = 10z -------(1)

14y + 10x = 9z -------(2)

Substract eq.(2) from eq.(1) we get 4x - 4y = z

put the value of z into eq.(1) we get the ratio of x and y =25:13 .
