Q1. Soni is 20 % heavier than rekha in weight. By how much percent is rekha lighter than soni?

Answer 1

rekha is lighter in weight 80%

Answer 2

Answer:

Rekha is 16.67% lighter than Soni      

Step-by-step explanation:

Let weight of Rekha be x kilograms

Now, Soni is 20% heavier than Rekha

⇒ Weight of Soni = x + 20% of x

                             = x + 0.2x

                              = 1.2x

Now, We need to find how much percent is Rekha lighter than Soni

Difference in both of their weights = 1.2x - x

                                                          = 0.2x

Now, Required Percentage = 0.2x/1.2x × 100

⇒ Required Percentage = 100/6

⇒ Required Percentage = 16.67 %

Therefore, Rekha is 16.67% lighter than Soni
