Mathematical interpretation for this question is that ;
7 × n/4 > 7
Dividing both sides by 7
n/4 > 1
Cross multiply
n> 1×4
n>4
The idea is this when you n = 4
7×n/4 = 7 × 4/4 = 7(this is not greater than 7)
Immediately you increase n by any value the answer gives a result greater than 7...
The relationship is that n must be greater than 4...
n>4...
Hope this helped.....
