Answers
Step-by-step explanation:
percentage of dogs caused by MCD = 15%×(100-10)=15%×90=13.5%
total dogs=6120×100/(100-10-13.5)
= 6120× 100/76.5
= 8000 dogs
The original number of dogs before the disease are 8000.
Step-by-step explanation:
Consider the provided information.
Let x represents the number of dogs.
It is given that 10% of dogs died.
10% can be written as 0.1.
That means remaining Dogs are: 1-0.1 = 0.9x.
Out of 0.9x dogs, 15% of the remaining caught by M.C.D.
That means out of 0.9x dogs 85% not caught by M.C.D.
85% can be written as: 0.85
Thus, 0.9x × 0.85 = 0.765x
The number of dogs left is 6120.
Therefore,
0.765x = 6120
x = 8000
Hence, the original number of dogs before the disease are 8000.
