(b) 2-3

(c) 4-5

(d) 6

This question was addressed to me during an online interview.

My doubt stems from Pattern Allowances in section Preventive Maintenance in Foundries & Metal Casting Process of Casting-Forming-Welding I

Answer 1

Right choice is (b) 2-3

Easiest explanation: A pattern is basically a duplicate of the object that we intend to cast. Patterns can be made up of wood, plastics or metals. A pattern is generally made up of two or three pieces, whereas it is casting which is in one piece.
