Question

What is the
refractive index of a mediun
if
the angle of incidence is 45° and
angle of refraction is
30°=? (Given
that sin 45°= 1/√2, sin 30°= 1/2​

Answer 1

⇒ 70,000 + 5,90,000 - 60,000

⇒ 6,00,000

Cost of Good Sold = 6,00,000

Gross Profit = Net Sales - Cost of Good Sold

⇒ Gross Profit = 7,20,000 - 6,00,000

⇒ 1,20,000

Gross Profit =1,20,000
