Answer: Option D

Explanation:

Let the points be A( - 4, 0), B(0, 5) and C(4, 0).

Now, AB = √{( - 4 - 0)² + (0 - 5)²} = √41

BC = √{(0 - 4)² + (5 - 0)²} = √41

CA = √{(4 + 4)² + (0 - 0)²} = 8

Here, AB = BC. So, the triangle will be an isosceles triangle.

Answer: Option C

Explanation:

Net income from gross income of 20,000 tk = 80% of 20,000 = (0.8)(20,000)

Net income from gross income of 30,000 tk = 80% of 30,000 = (0.8)(30,000)

So, the INCREASE in net income = (0.8)(30,000) - (0.8)(20,000)

= (0.8)(30,000 - 20,000)

= (0.8)(10,000)
