Answer 1

Answer:

22

Step-by-step explanation:

3+1+5+7=16

3+2+5+8=18+6=24

7+3+4+1=15+7=22

Answer 2

Given :-

→ 3,1,5,7 = 16

→ 3,2,5,8 = 24

To find :-

→ 7,3,4,1 = ?

Solution :-

First lets try to find the logic of given first two .

→ with 3,1,5 and 7 outcome is = 16

Logic :- Cube root of 2nd digit , than add all.

Check :- 3 + (1)³ + 5 + 7 = 16 (satisfy) .

Similarly, Now, checking Next :-

→ 3 + (2)³ + 5 + 8 = 3 + 8 + 5 + 8 = 24 (Satisfy).

Therefore, Now, we will apply same logic in Last .

we get :-

→ 7 + (3)³ + 4 + 1

→ 7 + 27 + 5

→ 12 + 27

→ 39 (Ans.) (None of The options.)

Hence, 39 is the correct Answer.
