Answer:
Number of stock A = 200
Number of stock B = 300
Step-by-step explanation:
Let :
Number of stock A shares = a
Number of stock B shares = b
Worth of stock A = 50 * a = 50a
Worth of stock B = 60 * b = 60b
50a + 60b = 28000 - - - (1)
Triple the value of stock B:
3 * 60 = 180
Value of stock A goes up by 50%
(100 + 50)% * 50 = 1.5 * 50 = 75
75a + 180b = 69000 - - - (2)
50a + 60b = 28000
75a + 180b = 69000
Multiply equation 1 by 3 and subtract
150a + 180b = 84000
75a + 180b = 69000
75a = 15000
a = 15000/75
a = 200
75(200) + 180b = 69000
15000 + 180b = 69000
180b = 69000 - 15000
180b = 54000
b = 300
Let the normal bicycling speed with no wind = x mph
So , speed with the wind = (x+2) mph
and speed against the wind = (x-2) mph
It means
Time taken in going with the wind = Distance/speed = 45/(x+2) hours
and
Time taken in going against the wind = 33/(x-2) hours
And Both times are same , according to the question
So
45/(x+2) = 33/(x-2)
On cross multiplying, we get
45(x-2) = 33(x+2)
45x-90 = 33x+66
Add 90 to both sides
45x -90 + 90 = 33x + 66 +90
45x = 33x +156
Subtract 33x from both sides
45x - 33x = 33x - 33x +156
12x = 156
Divide both sides by 12
x= 13
That implies
The normal bicycling speed = 13 Miles per hour
Answer:
$1950.74
Step-by-step explanation:
step 1
x(1 + 0.06/12)^5=2000
step 2
x= 2000/(1 + 0.06/12)^5
= 1950.741337
All numbers rounding up are 235, 236, 237, 238, and 239.
All numbers rounding down are 241, 242, 243, and 244.
If a number's last digit is 1-4, round down, and if it is 5-9, round up.
