If 0.13 × p2 = 13, then p is equal to?
Answer & Solution
Correct Answer:
Option
A
$$\eqalign{
& {\text{0}}{\text{.13}} \times {{\text{p}}^2} = 13 \cr
& \Rightarrow {{\text{p}}^2} = \frac{{13}}{{0.13}} \cr
& \Rightarrow {{\text{p}}^2} = \frac{{13}}{{13}} \times 100 \cr
& \Rightarrow {{\text{p}}^2} = 100 \cr
& \Rightarrow {\text{p}} = 10 \cr} $$
