Answer 1

Answer:

Explanation: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
