Solution:

Distance between PQ = 64 km

Distance covered on the 1st day = 64 2 = 32 km

Distance covered on the 2nd day = 32 2 = 16 km

Like wise Total distance covered = 32 + 16 + 8 + 4 + ..........

This is an infinite geometric series whose first term is 32 and common ratio = 1 2

∴ Sum of the infinite series = a 1 - r

Where a is the first term and r common ratio = 32 1 - 1 2 = 64

Hence the man will never reach Q

A can do a certain work in the same time in which B and C together can do it. If A and B together could do it in 10 days and C alone in 50 days, then B alone could do it in :

Solution:

A = B + C

⇒ A + B + C = 6 units

But A = B + C

⇒ 2(B + C) = 6 units

⇒ B + C = 3 units

⇒ B + C - C = 3 - 1 = 2 units

⇒ B = 2 units

Hence, B alone did it in:

50 2 = 25 days
