let cost price= X and given selling price= 150
loss = 4% of cost price= 4 X /100
loss = cost price- selling price
4X/100 = X - 150
X/25 = X - 150
X - X/25 = 150
24X/25 = 150
X= 150 x 25/24= 625/4 = 156.25
cost price = 156.25
for 20%. gain selling price should be 156.25+156.25 × 20/100 =
156.25 + 31.25 = 187.50
