11. The average temperature of Monday, Tuesday, Wednesday and Thursday was 38° and that of Tuesday, Wednesday, Thursday and Friday was 40°. If the temperature on Monday was 30°, the temperature of Friday was :
Monday temparature is 30. So T+W+Th=(152-30)=122
T+W+Th+F=(4×40)=160
F = (160-122)= 38°.
12. The average of weight of three men A,B and C is 84 kg. Another man D joins the group and the average now becomes 80 kg. If another man E, whose weight is 3 kg.more than that of D, replaces A, then the average weight of B,C,D and E becomes 79 kg. The weight of A is :
A+B+C+D= (4×80)=320
D = (320-252)=68 and E = (68+3)=71
Now, B+C+D+E = (4×79)=316
B+C+D=(316-71)=245 kg
So, A = (320-245)=75 kg.
13. The average age of 30 students in a class is 12 years. The average age of a group of 5 of the students is 10 years and that of another group of 5 of them is 14 years. The average of the remaining students is :
5×10+5×14+20×x=30×12
20x=360-120 or 20x=240 or x = 12
