QUESTION: 67

Let PQ = 64 km A man starts from P and walks 32 km on first day, on second day he walks only 16 km, on third day he walks 8 km, on fourth day he walks just half, i.e. 4 km. He will reach Q in
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 = 32/1/2 = 64
Hence the man will never reach Q
