YAHAN answer de de rha hun....okay...

$Let \: total \: Distance \: travelled \: be \: x \\ \\ A.T.Q \\ x = \frac {2x}{15} + \frac {9x}{20} + 10 \\ x = \frac {8x + 27x}{60} + 10 \\ x = \frac {35x}{60} + 10 \\ x = \frac {35x + 600}{60} \\ 60x = 35x - 600 \\ 60x - 35x = 600 \\ 25x = 600 \\ x = \frac {600}{25} \\ x = 24 Km = total journey$
