How many times, correct to the nearest whole number, will a man run round circular track of diameter 100m to cover a distance of 1000m?
-
A.
3 -
B.
4 -
C.
5 -
D.
6
Correct Answer: Option A
Explanation
No. of times = (frac{text{Total distance}}{text{Circumference of circle}})
= (frac{text{Total distance}}{pi d})
= (frac{1000m}{frac{22}{7} times 100m})
= (frac{1000 times 7}{2200} = 3.187)
= 3(approx.) nearest whole no.
