Select the option in which the numbers are related in the same way as are the numbers of the following set. 

{5, 15, 20}

{10, 13, 17}

{5, 15, 20}

The logic followed here is :

5 + 15 + 20 = 40

check in options

1)  {24, 8, 18} ⇒ 24 + 8 + 18 = 50 ≠ 40

2) {10, 13, 17} ⇒ 10+ 13 + 17 = 40 = 40

3) {4, 14, 24} ⇒ 4 + 14 + 24 = 42 ≠ 40

4) {9, 14, 19} ⇒ 9 + 14 + 19 = 42 ≠ 40
