I'm like a doll, But I'm not for playing; I stand up straight, but if windy I may be laying; I'm well-known and famous for having no brain; I work outside both day and night in sunshine or in rain. What am I?
A hundred stones are placed, in a straight line, a yard distant from each other. How many yards must a person walk, who undertakes to pick them up, and place them in a basket stationed one yard from the first stone?
To collect the stones, the person must walk 1 yard to pick up the first stone, and then they had to double the distance each time - 2 yards, 4 yards, 8 yards etc.
To find the answer we multiply 202 by 50 = 10,100 yards.
I can sizzle like bacon, I am made with an egg, I have plenty of backbone, but lack a good leg.
I peel layers like onions, but still remain whole, I can be long like a flagpole, yet fit in a hole.
What am I?
