Given, total rods = 75
Color | Total | Twisted | Clear |
Blue | 35 | 25 | 10 |
Red | 40 | 30 | 10 |
Now, we will find the probability.
A. Probability of a blue rod from the box =
B. Probability of a clear rod from the box =
C. Probability of a blue twisted rod =
D. Probability of a clear red rod =
E. Probability of a twisted rod =
Let, A took x seconds
B took (170-x) seconds.
According to question,
A took 110 seconds and B took (170-110)= 60 seconds.
Let, Fahim's age be x year
Shakib is 2x years old.
4 years ago Fahim was (x-4) years old and 4 years ago Shakib was (2x-4) years old
According to question
After 2 years, Fahim will be = 14+2 = 16 years old
And Shakib will be = years old
Total amount of charity =
Here, maximum 3 students can give = 25 Tk.
Total =
Minimum amount contributed by one student =
The sum of 15 consecutive integers will 88.
only when there are some positive and negative consecutive integers.
So, we let, the numbers are
According to question
The largest number is
But, here is not a integer.
So the data given in the question may not be consistent.
The number of 10 seat room = x
The number of 20 seat room = 40- x
According to question
Number of 10 seat room = 20 and number of 20 seat room = 40-20=20.
The ratio of the number of 10 seat room to the number of 20 seat room = 20 : 20= 1 : 1. ans.
Given, total football players 85
Do not score a goal = 85 - 42 = 43 players
Do not receive a yellow card = 85-54 = 31
players Do not score a goal or don't receive yellow card or do not do either = 43 +31-5=69
Number of players who scored a goal and received a yellow end = 85 - 69 = 16
Required fraction = 16/85 ans.
