Correct option is

C

5 km

Let the distance of his office be xkm and thr right time to reach office be t min

Time taken to reach office at 8km/hr =60t+2.5=8x (i)

Time taken to reach office at 10km/hr =60x−5=10x (ii)

Subtracting (ii) from (i) we get,

607.5=8x−10x

607.5=405x−4x

x=607.5×40

x=5km
