I'm stuck on a level in Think Different for android
This is the level that I'm stuck on:
42 15 14
56 35 8
36 ?? 4
I've spent a considerable amount of time on this level, but still can not figure it out.
Best Answer
The answer is 45.
Here's how you solve it:
To get the numbers in the first column, take the number in the third column and solve, eg. 42 = 14 * x, therefore x = 3. Multiply this number by y to get the 2nd column number. eg. 15 = y * 3 this yields y = 5.
First row:
42 = 14 * 3, 15 = 5 * 3
Do this for the second row as well:
56 = 8 * 7, 35 = 5 * 7
See that y is always 5 so for the third row find the x as per the previous two then use y = 5 to solve ??:
36 = 4 * 9, so ?? must be 5 * 9 ie. 45
