let x oranges purchased at rate 3 for 40

and same x oranges purchased at rate 5 for 60

oranges 3 for 40 costs 40/3 rs for one orange

so x oranges costs 40x/3 rs

oranges 5 for 60 costs 12 rs for one orange

so x oranges costs 12x rs

now total cost = 40x/3 + 12x

= 76x/3

total oranges purchased = 2x rs


now selling price is 3 for 50

so one orange price is 50/3

price of 2x oranges = 50/3 × 2x

= 100x/3

so gain is 100x/3 - 76x/3

= 24x/3

= 8x

now 76x/3 ---------- 8x
then 100 ----------- ???

solving , gain percentage = 100 ×8×3 × x / 76x

= 31.57 %
