Answer 2

4 25 49 169=14. 36 81 64 144=55 then 16 9 81 100 = 28

If the four numbers are a b c d, then the resulting number is produced as:

√a * √d  - (√b + √c)  = X, where X is the resulting no.

For 4 25 49 169,

a = √4 = 2

b = √25 = 5

c = √49 = 7

d = √169 = 13

So, X = √a * √d  - (√b + √c)  = 2 * 13 - (5 + 7) = 26 - 12 = 14, which is the first no.

So,  4 25 49 169 = 14.

For 36 81 64 144,

a = √36 = 6

b = √81 = 9

c = √64 = 8

d = √144 = 12

So, X = √a * √d  - (√b + √c)  = 6 * 12 - (9 + 8) = 72 - 17 = 55, which is the second no.

So,  36 81 64 144 = 55.

For  16 9 81 100,

a = √16 = 4

b = √9 = 3

c = √81 = 9

d = √100 = 10

So, X = √a * √d  - (√b + √c)  = 4 * 10 - (3 + 9) = 40 - 12 = 28, which is the third and the required no.

So,   16 9 81 100 = 28.
