Profit = Selling Price - Cost Price

= 540 - 470

= 70

Profit Percentage = (Profit ÷ Cost Price) × 100

= (70 ÷ 470) × 100

= 15 (14.89%)

Explanation

x = 7 — 4√3, we are required to find x + 1/x.

1/x = 1/(7 — 4√3)

Rationalising 1/x,

1/x = {1/(7 —4√3)} × {(7 + 4√3)/7 + 4√3)} = {(7 + 4√3)}/{7² — 4²(√3)²} = (7 + 4√3)/(49 — 48) = 7 + 4√3.

Therefore

x + 1/x = 7 — 4√3 + 7 + 4√3 = 14.

Explanation

When 52416 is divided by 312, the quotient is 168. To find the quotient when 52.416 is divided by 0.0168, we can set up a proportion:

52416 ÷ 312 = 168

52.416 ÷ 0.0168 = x

We can then cross-multiply and solve for x:

x = (52.416 × 312) ÷ 0.0168

x = 3120

So, the quotient is 3120.
