Question

1+4=5
2+5=12
3+6=21
8+11=?

Answer 1

Solution :

※ 1 + 4 = 5

[ 1 + ( 1 × 4 ) = 1 + 4 = 5 ]

※ 2 + 5 = 12

[ 2 + ( 2 × 5 ) = 2 + 10 = 12

※ 3 + 6 = 21

[ 3 + ( 3 × 6 ) = 3 + 18 = 21 ]

Similarly , We get

8 + 11 = 8 + ( 8 × 11 ) = 8 + 88 = 96

Hence,

The required answer is 96

Answer 2

Answer:

40

Step-by-step explanation:

• 1 + 4 = 5 --- (1)

• 2 + 5 = 12 --- (2)

                 = 5 + 2 + 5

                 = (1) + 2 + 5

• 3 + 6 = 21 --- (3)

                 = 12 + 3 + 6

                 = (2) + 3 + 6

• 8 + 11 = (3) + 8 + 11

                 = 21 + 8 + 11 = 40
