Question

2312=15
3615=44
4624=60
1426=60
1426=?​

Answer 1

Answer:30

Step-by-step explanation:The process is  

Let the values of the digit be a b c d.  

Then the process is (a+c)*(b+d)

For example for the first number which is 2312

then (2+1)*(3+2)=15

Answer 2

2312 = 15

3615 = 44

4624 = 60

1426 = 30

Solution:

Given that,

2312 = 15

3615 = 44

4624 = 60

1426 = ?​

We have to find the missing value

Let us analyse the pattern followed

$2312 = (2+ 1 ) \times (3 + 2) = 3 \times 5 = 15 \\\\ 3615 = (3+ 1) \times (6 + 5) = 4 \times 11 = 44\\\\4624 = (4+2) \times (6+4) = 6 \times 10 = 60\\\\Similarly\\\\1426 = (1 + 2) \times (4 \times 6) = 3 \times 10 = 30$

Pattern followed:

sum of first and third digit multiplied with sum of second and fourth digit

Thus 1426 = 30
