Answer:
Let Cost Price be x
Profit = 1/6 of Cost price (CP)
Selling Price = 318
Step-by-step explanation:
According to question :
CP + Profit = Selling Price
x + 1/6 × x = 318
Taking LCM on Left hand side
(6x + x)/6 = 318
7x/6 = 318
7x = 318 × 6
7x = 1908
X = 1908/7
x = Rs 272.60
Cost price = Rs 272.60 = Rs 273
Profit = Rs 318 - 273
= Rs 45
Profit percentage = profit / CP × 100
= 45/273 × 100
= 16%
Good luck
