A) 1 and 8
B) 2 and 6
C) 0 and 9
D) 2 and 7
E) 2 and 9


\(5n + 2 > 12\)

Or, \(5n > 10\)

Or, \(n > 2\)


\(7n - 5 < 44\)

Or, \(7n < 49\)

Or, \(n < 7\)

So, \(2 < n < 7\)

Thus, the values of n will be { 3 , 4 , 5 , 6 }

Hence, the correct answer will be between 2 and 7 , answer will be (D)

Bunuel

After rearranging the inequalities, we get:

2 < n < 7

The value of n must be between which numbers?

A) 1 and 8

Every possible value of n must be between 1 and 8, so this is true statement

Are there not two correct answers?
