Tricky Maths Puzzle 1+4=5, 2+5=12, 3+6=21, 8+11=? Can You Solve this
1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
8 + 11 = ?
Explanation :
There’s three different way to calculate the answer.
Method I.
1 + 4 ⇒ 1 + 1(4) = 5
2 + 5 ⇒ 2 + 2(5) = 12
3 + 6 ⇒ 3 + 3(6) = 21
8 + 11 ⇒ 8 + 8(11) = 96
Now, there is another method to calculate the answer by summing up the previous summation result with the digits.
Method II.
1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 4 + 7 = 32
32 + 5 + 8 = 45
45 + 6 + 9 = 60
60 + 7 + 10 = 77
77 + 8 + 11 = 96
Method III.
1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 8 + 11 = 40
Correct answer:
Method (I & II) ⇒ 96
Method III ⇒ 40
