Question

7 5 2 =33 3 6 3 =10 4 ? 8 =33

Answer 1

Answer:

? = 13

Step-by-step explanation:

7 5 2=33

(7 - 1) * (5 + 1 )  - (2 + 1)

= 6 * 6 - 3

= 36 - 3

= 33

3 6 3=10

= (3 - 1) * (6 + 1) - (3 + 1)

= 2 * 7 - 4

= 14 - 4

= 10

4 ? 8 =33

=> (4 - 1) * (? + 1)  - (8 + 1) = 33

=>  3 (? + 1) = 42

=> ? + 1 = 14

=> ? = 13

hence

4  13  8  = 33

Rule here is

a   b    c   = d

=> (a - 1) * ( b + 1)  - (c + 1) = d
