5) None of these
Ans: (1)
Solution;
6394.50/5800 = (1+R/100) square
441/400 = (1+R/100) square
(21/20) square = (1+R/100) square
21/20 = (1+R/100)
R= 5

11. The average age of 80 boys in a class is 15. The average age of a group of 15 boys in the class is 16 and the average age of another 25 boys in the class is 14. What is the average age of the remaining boys in the class?
1) 15.25
2) 14
3) 14.75
4) Cannot be determined
5) None of these
Ans: (1)
Total age (sum) of all 80 students = 80 x 15 = 1200
Total age (sum) of 15 students = 15 x 16 = 240
Total age (sum) of 25 students = 25 x 14 = 350
Total age (sum) of remaining 40 students = 1200 – ( 240 + 350 ) = 610
Average of remaining 40 students = 610/40 = 15.25
