Answer 2

Dear Student,

◆ Answer - (A)

No of people surveyed = 122

● Explaination -

Let x be no of people surveyed. Then percentage of people who brush twice is -

95 = 78% of x

95 = x × 78/100

x = 95 × 100/78

x = 121.8 ~ 122 people

Hence, 122 people were surveyed.

Thanks dear for asking. Hope this is helpful to you...
