Question

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%?

Answer 1

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%
