a girl spent 1/4 of her money on taxi fare and 2/3 of the remaining on drink. what original amount of money was
(a) spent
(b) left
What's the answer I did not understand
We can say
(A)= spent= 1/4×(1-2/3)=1/12
(B)left=(1-1/12)=11/12
HMMMM that is amazing who thought you
To find the original amount of money that the girl had, we can follow these steps:
Step 1: Let's assume the original amount of money the girl had is 'x'.
Step 2: The girl spent 1/4 of her money on taxi fare. This means she spent (1/4)*x on the taxi.
Step 3: After spending on taxi fare, she has (x - (1/4)*x) = (3/4)*x left.
Step 4: The girl then spent 2/3 of the remaining amount on drinks. So, she spent (2/3)*(3/4)*x on drinks.
Step 5: The remaining amount can be calculated as [(3/4)*x - (2/3)*(3/4)*x] = (3/4)*x - (1/2)*x = (3/4)*x - (2/4)*x = (1/4)*x.
Therefore, the amount left is (1/4)*x.
To find the values of (a) spent and (b) left, we need to know the original amount of money 'x'.
1/4 spent leaves 3/4
2/3 * 3/4 = 1/2
(a) 1/4 + 1/2 = 3/4
(b) duh
