Shubham   13 years AGO

let cost of 1 dozen banana and 1kg orange is = 5x
and cost of 1kg apple is = 5y
then the equetion becomes
15x+5y=145 or 3x+y=29
given conditions are
1. 5x > 20 or x>4 (with this condition possible values of x are 5,6,7,8 and 9)
2. y>x (by adding this condition in the previous step the value of x can be 5,6 and 7)

hence the no of possible solution with these condition is 3
