If 0.13 × p2 = 13, then p is equal to?
A. 10
B. 0.01
C. 0.1
D. 100
Answer: Option A
Solution (By Examveda Team)
$$\eqalign{ & {\text{0}}{\text{.13}} \times {{\text{p}}^2} = 13 \cr & \Rightarrow {{\text{p}}^2} = \frac{{13}}{{0.13}} \cr & \Rightarrow {{\text{p}}^2} = \frac{{13}}{{13}} \times 100 \cr & \Rightarrow {{\text{p}}^2} = 100 \cr & \Rightarrow {\text{p}} = 10 \cr} $$This Question Belongs to Arithmetic Ability >> Algebra
I think the question is wrong.. If the answer is 10 then it should be P² not P³.
