Answer 2

Answer:

80%

Step-by-step explanation:

Total students = 1050

⇒ Number of boys + Number of girls = 1050

⇒ Number of boys + 210 = 1050

⇒ Number of boys = 1050 - 210

⇒ Number of boys = 840

Percentage of boys = number of boysx 100 / Total students  

                                = 840 x 100 / 1050

                                 = 84000/ 1050

                                  = 8400 / 105

                                 = 80 %
