then cost of mango and orange per kg is given in btn 20 to 30
let the cost of mango per kg be rs.29
cost of orange per kg be rs.21
then cost of 5kg mango=5*29=rs.145

Let,
1kg mango=x Rs.
1kg orange=y Rs.

Given,

Hence, x=175-(X/2) and y=(X/2)-125

so X must be even.

Then answer is 292.

can be 292 as well as 303

let cost of mango be \'m\' and orange be \'o\'

m + o = 50
=> 5m + 5o= 250
but we have to find the total cost of 5m + 7o (5 mangoes and 7 oranges )
also, 20 < m,o < 30
=> 40< cost of two oanges 290 < 5m + 7o < 310
and both 292 and 303 satisfy this

sum of cost of 1 Kg mango and 1 Kg orange is Rs 50

sum of cost of 5 Kg mango and 5 Kg orange is Rs 250

5kg mango + 5kg orange + 2kg orange = x

hence, 250 + 2kg orange = x
2kg orange = x - 250
1kg orange = (x-250)/2

by adjusting rates between 20 to 30, choose option

solving we get x = 292 orange = 21rs and mango 29rs
