Answer:
Rs 175
Step-by-step explanation:
Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).
At Rs200, the profit is 200-x.
So we have an equation: minus 150 minus x is equal to 200 minus x.
To solve the equation, the cost price X is Rs175.
Answer:
262/365
Step-by-step explanation:
So as you can see there is no more information aout Kay on her birthday, so the chances of her birthday being on a week day is given by the total number of the weekdays of the year between the total number of days in a year, so in 2019 there are 262 weekdays, divided by 365 you get the probability that Kay´s birthday falls on a weekday.
262/365=,7178=71,78%
So the probability of Kay´s brithday falling on a week day will be 71,72%

Answer:
Below.
Step-by-step explanation:
a) A = {1, 2, 5, 10}
b) B = {1, 3, 5, 15}
c) A∩B = {1, 5} ( elements common to A and B).
d) A∪B = {1, 2, 3, 5, 10, 15} (total elements in A and B).
