Question

if 7+5+2=33/3+6+3=10 then 4 +?+8=33​

Answer 1

Answer:

13

Step-by-step explanation:

Given  

if 7+5+2=33 3+6+3=10 then 4 +?+8=33

Let the missing number be x

Now the given series can be written as

1. (7 -1) x (5 + 1) – (2 + 1) = 6 x 6 – 3 = 33

2. (3 – 1) x (6 + 1) – (3 + 1) = 2 x 7 – 4 = 10

3. (4 – 1) x (x + 1) – (8 + 1) = 3 x (x + 1) – 9 = 33

                                       = 3x + 3 – 9 = 33

                                       = 3x – 6 = 33

                                           3x = 33 + 6

                                            3x = 39

                   Therefore x = 13

Now the missing number is 13
