original price of machine one = x
2024/x = 120/100
x = 2024 x 100/120
x = 5060/3 = 1686.67
original price of machine one = Rs 1686.67
original price of machine two = y
2024/y = 80/100
y = 2024 x 100/80 = 2530
original price of machine two = Rs. 2530
Profit from machine one = 2024 - 1686.67 = 337.33
Loss from machine two = 2530 - 2024 = 506
He lost 506 - 337.33 = Rs168.67 in total transaction
His loss in % = 168.67/(1686.67+2530) x 100 = 168.67/4216.67 x 100
= 4% (approx.)
