Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes

Answer: 7788.50
Solving steps:
P = 7400, R = 10.5%, T = 6
F = P + P rt
P = 7400
R = 10.5%
T = 6
F = 7400 + 7400rt
7400 x (12 + 6 x 0.105/12
7400 x (12 + 0.63)/12
7400 x 12.63/12
93462/12
15577/12
15577/2 0.01
7788.50

Answer:
A cage holds 6 black cats and 9 white cats, if two cats escape what is the probability of both cats being white?
Step-by-step explanation:
This involves two events, each with their own probability. Because both the first AND the second have to happen for this problem, you will MULTIPLY the wo individual probabilities.
Total cats = 15, White cats = 9
Probability first escaped cat is white = 9/15
One white cat has now escaped, so we now have Total cats = 14, White cats = 8
Probability second escaped cat is white = 8/14
Now MULTIPLY because this is an AND probability problem. (9/15)(8/14) = 72/210 = 12/35
