Ans.
Note : Five digits from the top are available.
The position of the decimal point is decided by dividing R into groups of two digits
each counting from the decimal point.
Taking J 53987,
for example, 53987 is divided into three~ groups (5 :39 :87) counting
from the decimal point. The decimal point of the answer, therefore, must be placed
between the t hi rd* and the fourth digit counting from the left. The answer is 232.35.
