Let cost price of bag 1 be ‘x’ and cost price of bag 2 be ‘y’.
Now, we have,
x + 25x/100 = 2500
⇒ 5x/4 = 2500
⇒ x = Rs. 2000
y – 20y/100 = 2500
⇒ 4y/5 = 2500
⇒ y = Rs. 3125
⇒ Total CP = x + y = 2000 + 3125 = 5125
Total SP = 2500 + 2500 = Rs. 5000
∴ Loss percentage = (5125 – 5000)/5125 × 100 = 2.43%
Thus, the correct answer is option 2.
