Hi, check the comment. It is the answer. I wrote my own comment and rated myself 1.0 for no reason lol!! (Oh mah gawd I was joking this is not the answer, do NOT take this as your answer!
Let,the time taken by larger pipe = x
By smaller pipe = x+5
It would be: 1/x + 1/(x+5) = 9/100
= x+5+x /(x)(x+5) = 9/100
= 2x+5 / x²+5x = 9/100
= 100(2x + 5) = 9(x² + 5x)
= 200x + 500 = 9x² + 45x
= 9x² - 155x - 500 = 0
= 9x² - 180x + 25x - 500 = 0
= 9x(x - 20) + 25(x - 20) = 0
= (9x + 25) (x - 20) = 0
= x = -25/9 or x = 20
Time can't be in negative so -25/9 is rejected.
Now,x + 5 = 20 + 5 = 25
In short, Your Larger pipe takes 20 minutes and smaller pipe takes 25 minutes
Hope this helps!
Answer:
Nominal interest rate is = 9% converible quaterly
we need to find monthy effective interest rate
0.09
i = 0.00744 or 0.75% approximately
i can also be taken as = 0.09/12
now PV of annuity will be the market price i.e x
6 60 *2 ---------------------a
Multiply equation by \frac{1}{1+i} both sides
6 60 2 PV ---------------b
Subtract equation b from a
60 2 PV (1 1+i (1+2)1 (1+2)2 (1+2)3 (1+2)60 (1+961
60 2 PV( 1 +i
on putting i = 0.00744
PV = 2733.88 approximately
X = 2733.88
