**********************************************************

The logic is;

(sum of the positional values of the opposite letter x no. of vowels in word)

So,

LABOUR        (vowels; A, O, U)

L → O(15)

A → Z(26)

B → Y(25)

O → L(12)

U → F(6)

R → I(9)

Thus, 15+26+25+12+6+9 x3= 279

And,

EXHALE            (vowels; E, A, E)

E → V(22)

X → C(3)

H → S(19)

A → Z(26)

L → O(15)

E → V(22)

Thus, 22+3+19+26+15+22 x3= 321

Similarly,

CAUTIOUS          (vowels; A, U, I, O, U)

C → X(25)

A → Z(26)

U → F(6)

T → G(7)

I → R(18)

O → L(12)

U → F(6)

S → H(8)

Thus, 25+26+6+7+18+12+6+8 x5= 535
