Step-by-step explanation:
Let the initial price of machine be 100
SP of wholesaler = 100 +(100*20/100) = 120
CP for shopkeeper = 120
SP for shopkeeper = 120 +( 120*25/100) = 150
Difference in Sp of the shopkeeper and the wholesaler is 150-120 = 30
According to question
30 = 129
100 = 430
Therefore the initial price of the machine is Rs430
