Course : CA Foundation

Topic : Ratio

 

Learning Objective:

  • How to find duplicate ratio?

Concepts:

  • A ratio is a comparison of the sizes of two or more quantities of the same kind by division.

  • If p and q are two quantities of the same kind, then the fraction p/q is called the ratio of p to q.

  • The quantities p and q are called terms of the ratio.

Properties of Ratio:

  • The duplicate ratio of a : b is a² : b²

 

Exercise 1(A):

  • Option (A) : p² = 6st

  • Option (B) : p = 6st

  • Option (C) : 2p = 3st

  • Option (D) : None of these
