Answer: Option C Here we have to verify the given two conditions for the given options. Condition :1 As given, after finished his purchase he had the rupees as much as the paise when he went. Condition :2 After finishing purchase, he had Half as many rupees as he had paise when he went. We solve it through option checking method. Case :1 Now suppose the answer is option c Then he spent Rs. $$\frac{{99.98}}{2}$$ = Rs. 49.99 Condition :1 Here we have 99 paise so the rupees should be 99 when he went. He initially had 99 Rs. Hence condition 1 is satisfied. Condition :2 He had 98 paise to begin with. So the rupees he spent should be $$\frac{{98}}{2}$$ = Rs. 49 as per condition 2.
