SSC Constable GD Paper 22 Feb 2024 (Reasoning)

Solution :

Let
M -> + (Addition)
N -> + (Addition)
O -> (divide)

17 M 18 N 55 O 5 = 46
17 + 18 + 55 5 => 17 + 18 + 11= 46

68 M 13 N 65 O 13 =86,
68 + 13 + 65 13 => 68+13+5 = 86

Apply same rule to

40 M 70 N 85 O 17 = ?
40 + 70 + 85 17 = ? 40+70+5 =115

Answer is 115
