Mrs. Williams has a certain number of coins in her bag in denominations of 25 cents, 50 cents and $1. If she has a total of $5 in her bag, what is the number of 25 cents in her bag? Given that she has at least one coin of each denomination. ($1 = 100cents)
(1) Number of $1 coins = number of 50 cent coins > number of 25 cent coins.
(2) The number of $1 coins is 23 of the number of 50 cent coins.
So i went for A, Now when i read the 2nd statement, its not clear what it meant by
23 of the number of 50 cent coins.
Statement 1, can be solved very easily
x = number of 25 cents, y number of 50 cents and z number of 1 dollar
0.25 x + 0.50 y + 1 z = 5.00
25x + 50 y + 100z = 500
Number of $1 coins = number of 50 cent coins > number of 25 cent coins.
y=z > x, can only be true when you take values as y=z= 3 and x =2
50 + 150 + 300 = 500.
Sufficient.
OP do share your thoughts.
