Answer 2

Answer:

16 and 56

Step-by-step explanation:

a) In first month he sold 40 lunch boxes so loss incured from lunch boxes =

10*40 = 400

as it is told that there is no profit no loss so Geometry box sold by him =

$\frac{400}{25}$ = 16

b) In sexond month he sold 20 geometry boxes so profit made by him =

25*20 = 500

as it is told there is a loss of Rs. 60 so lunch box sold by him =

$\frac{560}{10}$ = 56
