B is the answer, 50
You can use an estimation here, 26≈25% ≈ 1/4
The total number has to be ≈ 4 ×13 ≈ 52, which is nearest to 50, as we see here

Hey,
Thanks for asking this question.
Lets suppose N number of people were surveyed.
Since 26% of N is 13,
=> N×(26/100) = 13
=> N = (13×100)/26
=> N = 50
So total 50 people were surveyed.
●Hope my answer help

what is the equation of the line passing through 0,6 and 3,0
a.y=-1/2x+6
b.y=-1/2x+3
c.y=-2x+6
y=-2x+3
a.y=-1/2x+6
b.y=-1/2x+3
c.y=-2x+6
