a) Rs. 75.50
b) Rs. 98.98
c) Rs. 99.98
d) None of these
Answer: c
Explanation: 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.
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.
It turns out that the rupees actually he spent was 49.
Therefore, condition 2 is satisfied as well.
