If the price of sharpeners reduces by 20%, a girl can purchase 3 more sharpeners in a dollar. The number of sharpeners that can be purchased in five dollars is?
- 75
- 65
- 55
- None of these
Explanation
Price becomes cheap, so you get 3 extra in $1.
Let old price = 100 cents
New price = 80 cents (20% less)
Old qty in $1 = let's say = x
New qty in $1 = x + 3
Money spent is same $1, so:
x _ 100 = (x+3) _ 80
100x = 80x + 240
20x = 240
x = 12
So old = 12 sharpeners in $1
New = 12+3 = 15 sharpeners in $1
For $5
Old = 12 x 5 = 60
New = 15 x 5 = 75
