Question

A = {1, 2, 3, 4}, B = {-1, 2, 5, 6} and R = {{a, b) / a < b, a E A, bE B} then range of R is (A) {2, 5, 6} (B) A (C) B (D) Ø​

Answer 1

Answer:

Steps:

1) Draw a line segment AB of length 9.3 units.

2) Extend the line by 1 unit more such that BC=1 unit .

3) Find the midpoint of AC.

4) Draw a line BD perpendicular to AB and let it intersect the semicircle at point D.

5) Draw an arc DE such that BE=BD.

Therefore, BE= 9.3
