Answer:
0.25 % loss.
Step-by-step explanation:
Let the cost of 1 watch be rs x then the cost of the other is rs 400 - x.
Let the sp be rs y.
So we have:
y = x + 0.05x
y = (400 - x) - 0.05(400 - x)
y = 400 - x - 20 + 0.05x
y = 380 - 0.95x
So x + 0.05x = 380 - 0.95x
2x = 380
x = 190.
and y = 190 + 0.05*190 = 199.5.
So the total selling price = 2 * 199.5 = rs 399
So final loss is [ (400-399)/ 400] * 100
= 0.25 %.
Answer:
15 goals out of 50 penalty kicks was scored by brock
Step-by-step explanation:
If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:
Number of goals scored = probability value * total penalty kicks taken
Number of goals scored = 
Number of goals scored = 
Answer:
I think the answer is undefined because the question above is an expression of f of x not a statement of variation which should have a constant of proportionality
Answer: 9
