How to find x² if p : q is the sub-duplicate ratio of p - x² : q - x²?

Course : CA Foundation

Topic : Ratio

 

Learning Objective:

  • How to find values with sub-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 sub-duplicate ratio of a : b is √a : √b

 

Exercise : 1(A)
