Select the number that will replace the question mark.

Row 1

Third number = $$\sec ond\ number\ \times\ \frac{\sec ond\ number}{first\ number}\ -1$$

= $$16\times\frac{16}{4}\ -1$$
= $$16\times4\ -1$$

= 64-1

= 63

Row 3

Third number = $$\sec ond\ number\ \times\ \frac{\sec ond\ number}{first\ number}\ -1$$

= $$48\times\frac{48}{8}\ -1$$
= $$48\times6\ -1$$

= 288-1

= 287

Row 2

Third number = $$\sec ond\ number\ \times\ \frac{\sec ond\ number}{first\ number}\ -1$$

= $$35\times\frac{35}{7}\ -1$$
= $$35\times5\ -1$$

= 175-1

= 174

Hence 174 will come in place of question mark.
