YOUR ANSWER IS
FOR QUESTION 19
no of 2nd days= 183
no of 3rd days = 122/2(that were already in second day) =61
no of 5th day= 25
total no of days in leap year=366
no of days activities done= 183+61+25=269
sid didnot go for activities for (366-269)=97 days
hope it helps
Answer:
Step-by-step explanation:
The best way to solve this is by taking them as sets.
n(S) =Number of days Sid swims= 366/2=183
n(G)=Number if days Sid gyms=366/3=122
n(J)=Number of days Sid jogs=366/5=73.2=73
Then we can take intersections-
No. of days Sid:
swims and gyms=366/2*3=61 days
gyms and jogs=366/3*5=24 days
swims and jogs= 366/2*5= 36 days
does all three=366/2*3*5=123 days
now that we have all the information
A. No. of days Sid jogs only= 73-(36+24)+12=25(D)
B. No. of days Sid does not go for all the three activities?
we can take it as n'(SUGUJ)
which according to the formula is universal set(366)-no. of days he does any three activities(183+73+122-61-36-24+12=269) i.e., 366-269=97days
C. Total calories when he did all three activities= 12(130+110+140)=4560
hope this helps :)
