\(\frac{1}{6}\) th & \(\frac{1}{8}\) th Income of Martina = \(\frac{1}{3}\) rd & \(\frac{1}{4}\) th Income of Pam

\(\frac{1}{6}\) th = Half of \(\frac{1}{3}\) rd &

\(\frac{1}{8}\) th = Half of \(\frac{1}{4}\) th

Above itself means that Income of Martina is twice that of Pam

Say Income of Pam = 120

Then income of Martina = 240

\(\frac{1}{3}\) rd & \(\frac{1}{4}\) th of 120 = 40 + 30 = 70;

Balance for Pam = 120 - 70 = 50 ........... (1)

Balance for Martina = 240 - 70 = 170......... (2)

Total 10 months combined = (1) + (2)

= 220

\(Fraction = \frac{220}{360} =\frac{11}{18}\)

Answer = D
