Question

After getting a 20 percent discount, Jerry paid $100 for a bicycle. How much did the bicycle originally cost?

A. 80$
B. 82$
C. 116$
D. 120$
E. 125$

BrentGMATPrepNow · Answer

Let the original price = x
So, the discounted price = x - (20% of x) = x - 0.2x =   0.8x

If Jerry paid the discounted price of $100, we can write:   0.8x   = 100 
Solve: x = 100/0.8 = $125

Answer: E

Charli08 · Answer

If he got a 20% discount that means  he paid 80% of the original price . So:

80% of x = 100

80x/100 = 100

4x/5 = 100

x = 100*5 / 4

x = 125

==>  E

stne · Answer

So  .80  of some amt.  = 100

Amt  = \frac{100}{.80} = \frac{10000}{80}= 125

Ans E

Hope it's clear.

Sr1994 · Answer

If the discount is 20 per cent, we can say that the remaining 80 per cent = $100

ie, X *  \frac{80}{100}  = 100

80X = 10000
X =  \frac{10000}{80}

X =  125

Answer E
