Answer:
y = 541
Step-by-step explanation:
The mean is calculated as
mean = 
Mean of set A = 
= 
= 266
ratio between means = 7 : 12, then
mean of set B = 
× 266 = 456 , thus
= 456 ( multiply both sides by 5 )
1739 + y = 2280 ( subtract 1739 from both sides )
y = 541
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
