10 - x a b 16 - x 11 - x c
a + 10 + (16 – x) = 25 a = x – 1 x - 1 a b c
a + 10 + (16 – x) = 25 a = x – 1 b + 10 + (11 – x) = 34 b = x + 13 x + 13 b c
a + 10 + (16 – x) = 25 a = x – 1 b + 10 + (11 – x) = 34 b = x + 13 37 + (x – 1) + (10 – x) + (x + 13) = 74 – 8 59 + x = 66 x = 7
a + 10 + (16 – x) = 25 a = x – 1 b + 10 + (11 – x) = 34 b = x + 13 37 + (x – 1) + (10 – x) + (x + 13) = 74 – 8 59 + x = 66 x = 7

Try x = 4? Needs to be 74
Now Try x = 7? Bingo !!! x = 7 74 – 71 = 3 and4 + 3 = 7Is this a coincidence?

25 + 34 + 37 = 96 A + B + C = 66 96 – 66 = 30 Surplus 10 + 16 + 11 = 37 7 37 – 30 = 7 Surplus Find: = 7
