The value is 57.
Option (A) is correct.
Step-by-step explanation:
3, 3, 4, 5
3 + 3 + 4 + 5 = 15
Multiply the sum by 2
15 x 2=30
Take the square of 1st even number i.e 2
30 - (2)^2 - 5 = 21
21 × 3 = 63
Similarly
8 + 4 + 4 + 3 = 19
19 x 2=38
Now take the square of (4)^2
38 - (4)^2 - 5 = 17
17 x 3=51
Now For 9,9,7,5
9 + 9 + 7 + 5 = 30
30 x 2 = 60
60 - (6)^2 - 5 = 19
19 x 3 = 57
