I do A and B but that is the way I learned it. Hope this helps :)
Answer:
the cost price of manufacturer = RS. 14.80
Step-by-step explanation:
the retailers profit = profit percent of sold amount
= 25% of 30.09
= 25/100 × 30.09
= 7.5225
here, the cost price of retailer =
sold amount- profit amount
or, CP = 30.09 - 7.5225
= 22.5675
now, profit of whole seller =
profit% of sold amount
or, 20% of SP
20/100 × 22.5675
= 4.5135
CP = SP - Profit
or, CP = 22.5675- 4.5135
CP = 18.054
now, profit of manufacturer = profit℅ of SP
= 18% of 18.054
= 18/100 × 18.054
= 3.24972
or, CP of manufacturer = SP - profit amount
= 18.054 - 3.24974
= 14.80428
Therefore, cost price of manufacturer = 14.80
<span>You forgot to tell us how much the tickets cost each.
So I just arbitrarily chose that the price of a student
ticket is $4 and the price of a non-student ticket is $6.
<span>Let the number of student tickets be x
Let the number of non-student tickets be y
Price Money
Type Number of from
of of EACH ALL
ticket tickets ticket tickets
-------------------------------------------
student x $4 $4x
non-student y $6 $6y
-------------------------------------------
TOTALS 48 ----- $220
The first equation comes from the second column.
x + y = 48
The second equation comes from the last column:
4x + 6y = 220
So we have this system of equations:
.
We solve by substitution. Solve the first equation for y:
x + y = 48
y = 48 - x
Substitute (48 - x) for y in 4x + 6y = 220
4x + 6(48 - x) = 220
4x + 288 - 6x = 220
-2x + 288 = 220
-2x = -68
x = 34 = the number of student tickets.
Substitute in y = 48 - x
y = 48 - (34)
y = 14 non-student tickets.
Checking: 34 student tickets brings in $136 and 14 non-students is $84
That's 48 tickets.
And indeed $136 + $84 = $220
