6 out of 50
 

On a straight road XY, 100 m long, five heavy stones are placed 2 m apart beginning at the end X. A worker, starting at X, has to transport all the stones to Y, by carrying only one stone at a time. The minimum distance he has to travel is



A 472 m
B 422 m

C 744 m
D 860 m

Ans. D

Every trip will need more than 180 m and there are trips. hence, the distance covered will be greater than 750 m for which there is only one option = 860.

Alternative Method

For the first stone, he will cover 100 m.

For second, 200 4 = 196

For third, 200 8 = 192

For fourth, 200 12 = 188

For fifth, 200 16 = 184

Hence, the total distance = 860 m
