If 28 tiles is placed in 7 rows then each row has 4 tiles.
<u>Step-by-step explanation:</u>
The total number of tiles given =28.
The number of rows = 7.
The number of tiles in each row is given by diving the total number of tiles given by the number of rows.
No of tiles in each row= .
No of tiles in each row = .
No of tiles in each row = 4.
Note: You can replace the values according to the given values.
Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.
Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,
So we check, but
which means m must be bigger.
So we pick m to be 8 and check, but
which means m must be smaller.
Since only natural number between 6 and 8 is 7 we pick m to be 7 and check, and
.
The answer is therefore 7.
Hope this helps :)
