For which of the following applications are precise geometric constructions not necessary?
Building construction
Design of tools
World maps
None of These
World maps are generally not drawn to perfect scale. Hence precise geometric constructions are not necessary for world maps.
While constructing quadrilateral PQRS with 3 sides and 2 diagonals which of the following geometric tool is not used?
For drawing a geometric construction, 2 instruments are enough.
The best average for constructing an index number is:
(A) Harmonic mean (B) Arithmetic mean (C) Geometric mean (D) None of these
