A) \[p+5=9\]
B) \[14-p=10\]
C) \[\frac{20}{p}=4\]
D) \[9p=36\]
Correct Answer: C
Solution :
(a) \[p+5=9\,\,\Rightarrow p=9-5=4\] (b) \[14-p=10\Rightarrow p=14-10=4\Rightarrow p=4\] (c) \[\frac{20}{p}=\frac{4}{1}\Rightarrow 20=4p\] or \[4p=20\Rightarrow p=5\] (d) \[9p=36\Rightarrow p=\frac{36}{9}\text{=}4\] \[\therefore \] Option (c) does not have 4 as a solution.You need to login to perform this action.
