Let the two numbers be : P and Q

Given - The Two numbers are in the ratio 5 : 3


:\implies \mathsf{(P)/(Q) = (5)/(3)}


:\implies \mathsf{P = (5Q)/(3)}

Given : The Difference of two numbers is 18


:\implies P - Q = 18

Substituting the value of P in the above Equation, We get :


:\implies \mathsf{(5Q)/(3) - Q = 18}


:\implies \mathsf{(5Q - 3Q)/(3) = 18}


:\implies \mathsf{(2Q)/(3) = 18}


:\implies \mathsf{(Q)/(3) = 9}


:\implies \mathsf{Q = 27}

Substituting the value of Q in Equation P - Q = 18, We get :


:\implies P - 27 = 18


:\implies P = 27 + 18


:\implies P = 45

Answer : The Two Numbers are : 45 and 27
