A tree on first day grows 1/2 of its size second day 1/3 of its size on the previous day similarly than 1/4 and so on..U have calculate after how many days the tree will be 100 times of original size.	Choose the most appropriate option: A) 188 days B) 198 days C) 178 days D) 168 days E) 158 days
suppose 'x' is initial size and 'n' is no. of days.   1st day increment in size of tree = (1/2)x   After 1st day , size of tree = x+(1/2)x= (3/2)x   2nd day increment in size of tree = (1/3)*(3/2)x=(1/2)x   After 2nd day , size of tree = (3/2)x+(1/2)x=2x   3rd day increment in size of tree (3/2) +(1/2)= 
<gadget id="calculator">(3/2) +(1/2)</gadget>
<output>2</output>
2x   3rd day increment in size of tree=(1/4)*2x=(1/2)x   After 3rd day , size of tree = 2x+(1/2)=(5/2)x   It is clear that every day tree grows (1/2)x in size.   therefore , according to given condition   x+ (1/2)x*n=100x   n=198 days.   ANSWER:198 days
<result>B</result>
