Question:
- A vendor sells 60 percent of apples he had and throws away 15 percent of the remainder. Next day he sells
50 percent of the remainder and throws away the rest. What percent of his apples does the vendor throw?
(1) 17
(2) 23
(3) 77
(4) None of these
Correct Answer - (2)
Solution:
Let the number of apples be 100.
On the first day he sells 60% apples ie.,60 apples.Remaining apples =40.
He throws 15% of the remaining i.e., 15% of 40 = 6.Now he has 40-6 = 34 apples
The next day he throws 50% of the remaining 34 apples i.e., 17.
Therefore in all he throws 6+17 =23 apples.
