Explanation

Outer area = 50 × 30 = 1500 m²

Inner length = 50 - 2(5) = 40 m

Inner width = 30 - 2(5) = 20 m

Inner area = 40 × 20 = 800 m²

Path area = 1500 - 800 = 700 m²

CP = 10 × 120 = 1200

SP = 10 × 126 = 1260

Profit = 1260 - 1200 = 60

Profit% = (60/1200) × 100 = 5%

Explanation

Let actual price = x

Discount = 20% of x = 0.2x

Selling price = x - 0.2x = 0.8x

0.8x = 64000

x = 64000 / 0.8 = 80000

Explanation

Let CP = 100

MP = 100 + 30% of 100 = 130

Discount = 20% of 130 = 26
