Question

In a certain hospital, the mean birth rate of a week was 35. If the mean birth rate from Monday to Thursday was 32 and that of Thursday to Sunday was 36, find the number of births on Thursday.​

Answer 1

Answer:

27 births

Step-by-step explanation:

Mean = Total Birthss / NoOf Days

$35 = Total births \div 7$

=> Total deaths this week = 245

=> deaths on mon , tues , wed , thurs , fri , sat and sun = 245 ---> (1)

Similarly , from Monday to thursday

32 = No Of births on mon , tues , wed and thurs/4

=>Births on Mon , tues , wed and thurs = 128 ---> (2)

Again , from Thursday to Sunday ,

36 = No of births on Thurs, fri , sat and sunday/4

=> Births on Thurs , fri , sat and sun = 144 ---> (3)

Adding (2) and (3) ,

Births on Mon , tues , wed , 2(thurs) , fri , sat and sun = 128 +144 = 272 ---> (4)

On subtracting (1) from (4);

Thursday Births = 272-245 = 27

I hope you understand the answer now !
