Step-by-step explanation:

Given  

By what percent will the product of two numbers increase if one of them is increased by 30% and the other is increased by 20%?

  • Let the two numbers be a and b
  • Their product will be ab
  • One of them is increased by 30% so it will be 100 % a + 30% a
  •                                                                   = a +0.3 a
  •                                                                    = 1.3 a
  • Similarly 20% increase in b will be 1.2 b
  • So product will be 1.3 a x 1.2 b = 1.56 ab
  • Now previous product was ab.
  • Therefore percentage increase will be (1.56 ab – ab) x 100 %
  •                                                              = 0.56 x 100
  •                                                               = 56%
