Question

Manon's income increased by 20 % and then decrease by 20%​

Answer 1

Answer:

Step-by-step explanation:

Let, his income be Rs.100

After increase of 20% = 20% of 100 + 100

                        = 20+ 100=Rs.120

After decrease of 20% = 120 - 20%of 120

                      = 120 -24 =Rs.96

net decrease= 100-96= Rs.4 % = 4/100 x 100  = 4%
