Answer 1

Answer:

1. 8+1+8=17=1+7=8
2. 7+0+7=14=1+4=5
3. 4+5+2=11=1+1=2
4. 1+2+4+7=14=1+4=5

so the answer is 5......

Answer 2

Missing number (?) = 5

Step-by-step explanation:

We have,

818 = 8, 707 = 5 , 452 = 2

To find, 1247 = ?

The pattern follow:

Sum of all numbers ⇒ Sum of the digits

818 = 8 + 8 + 1 = 17

Sum of the digits = 1 + 7 = 8

707 = 7 + 0 + 7 = 14

Sum of the digits = 1 + 4 = 5

452 = 4 + 5 + 2 = 11

Sum of the digits = 1 + 1 = 2

Similarly,

1247 = ? = 1 + 2 + 4 + 7 = 14

Sum of the digits = 1 + 4 = 5

∴ Missing number (?) = 5
