1. If 1 + 9 + 11 = 1, Then what is the value of 12 + 11 + 9 = ?

Answer : 10

Explanation :

Equation 1 + 9 + 11 = 1 can be derived from
One (o) + nine (n) + eleven (e) = one => 1
Similarly for equation,
12 + 11 + 9
Twelve (t) + eleven (e) + nine (n) => ten (10)

2. Can you find the missing number in the number series below?

1, 18, 136, 959, 5748, ? , 114976, 344931

Answer :

28745

Explanation :

The formula used here is..

New Number = (Last Number +1 ) * 9

and Then New Number = (Last Number - 1 ) * 8 and so on.

(i.e)

1

(1+1) * 9 = 18

(18-1) * 8 = 136

(136+1) * 7 = 959

(959-1) * 6 = 5748

(5748+1) * 5 = 28745

(28745-1) * 4 = 114976

(114976+1) * 3 = 344931
