Answer:
option b -290
Step-by-step explanation:
price=?=x
cost=174
discount= 25% of price
profit= 25% of cost
profit + cost = price + discount
profit + 174 = x + [(25/100) × x]
174 + [(25/100)×174] = x + x/4
futher on solving :
174 + 43.5 = x + x/4
217.5 = x + x/4
870 = 4x - x
870 = 3x
x = 870/3
x = 290
