Question

4 8 12 =14 , 6 24 30=6, 2 7 8= ?

Answer 1

Final Answer : 15

Steps:
1) 4 8 12 : - 14
Sum : 4+8+12 = 24 :
Then, Unit digit of 24 ,u = 4 ,
Ten's Digit of 24,t : 2

We observe that,
(u*t )+ (u+t ) = (2*4)+(2+4) = 14

2) 6 24 30 :- 6
Sum = 30+24+6 = 60
u = 0 , t = 6

We observe,
(u*t ) + (u+t) = 0*6 + 0+6 = 6

3) Similarly,
2 7 8 :
Sum = 2+7+8 = 17

We got,
(u*t) +(u +t )= 7*1 + 7+1 = 15

Hence, Our Answer is 15

Answer 2

Given,

1. 4, 8, 12

Sum of numbers = 4 + 8 + 12 = 24

24 = product of digits + Sum of digits

= 4*2 + 4+2

= 14

2 . 6 24 30

Sum of Numbers = 6 + 24 + 30 = 60

60 = Product of digits + Sum of digits

= 6*0 + 6 + 0

= 6

3. 2, 7, 8,

Sum of Numbers = 2 + 7 + 8 = 17

17 = Product of digits + Sum of digits

= 7*1 + 1 + 7

= 15
