Answer:
CP of 1bulb =Rs10
CP of 250bulbs=Rs2500
Number of defective bulbs 12
remaining bulbs =250−12=238
SP of 1bulb =Rs12
SP of 238bulbs=Rs2856
profit=Total SP-CP=2856−2500=Rs356

Step-by-step explanation:
Given that the ratio of three trays is A : B : C = 2 : 3 : 4
Let us consider the common factor among the number of trays be "x".
If we need to make a total of 171 trays, then the equation of sum of trays would be :-
Type A + Type B + Type C = 171
2x + 3x + 4x = 171
9x = 171
x =
= 19
So we have following number of trays :-
Number of type A trays = 2x = 38 trays.
Number of type B trays = 3x = 57 trays.
Number of type C trays = 4x = 76 trays.
Now if each tray contains 20 cookies, then we would have following arrangements :-
Cookies in type A trays = 38×20 = 760 cookies.
Cookies in type B trays = 57×20 = 1140 cookies.
Cookies in type C trays = 76×20 = 1520 cookies.
Answer:
The radicand is whatever is under the the radical, so in this case, your answer would be D. 3x-5
Answer:
b < 5
Step-by-step explanation:
-2+b<3
Add 2 to each side
-2+2+b<3+2
b < 5
