If 14.287628762876........ can be represented in pq form, then 'p - q ' is ________.


Options:
A .   132863
B .   142862
C .   142876
D .   142863
Answer: Option A
:
A

Let 'x' = 14.287628762876 ------- (i)
then 10000x = 142876.287628762876 --------(ii)
Subtracting (i) from (ii) we get
10000x - x = 142876.287628762876  - 14.287628762876
9999x = 142862
 then 'x' = 1428629999  
p = 142862, q = 9999
So, p-q = 132863
