Question

A mobile phone shop has 168 phones on display. If they were displayed equally in 6 glass cases, how many phones were there in each case?

Answer 1

Hint: A total of 168 phones are on display in a mobile shop and these phones were displayed equally in 6 glass cases. Let us assume that “x” phones are in each glass case so multiplying x with 6 is equal to the total number of phones which is given as 168. So, dividing 168 by 6 we get the number of phones in each case.

Complete step-by-step answer:
It is given that 168 mobile phones are on display and also given that they were displayed equally in 6 glass cases and we are asked to find the number of mobile phones in each case.
Let us assume that there are “x” phones in each glass case so multiplying x by 6 we get,
$x\left( 6 \right)$
Now, equating the above number of phones to the total phones (which are 168) we get,
$6x=168$
Dividing 6 on both the sides of the above equation we get,
$\begin{align}
  & x=\dfrac{168}{6} \\
 & \Rightarrow x=28 \\
\end{align}$
From the above solution, we have got the value of x as 28. As we have assumed that the number of phones in each glass case is x so 28 phones are displayed in each glass case.

Note:To crack this problem, you should understand what this line “they were displayed equally in 6 glass cases” in this problem means. If you could understand this line well then the problem is pretty simple. As the line is saying that the mobile phones were displayed equally in 6 glass cases so the number of phones in each glass case is equal due to which we have assumed that x phones are displayed in each case.
