2 times the sum of three number is : 

5,52 + 12,25 + 11,63 = 29,4

The sum of three numbers is : 

29,4 : 2 = 14,7

The first number is : 

14,7 - 11,63 = 3,07

Answer : 3,07

Đơn giản

The first number is: (27+3) : 2= 15

The third number is: 27- 15=12

The second number is:15x4=60

Average of three numbers is: (15+12+60):3=29

        Answer:29

The first 100 positive even numbers are 2; 4; 6;...; 200. Their sum is \(\dfrac{\left(200+2\right).100}{2}=10100\).

The first 100 positive odd numbers are 1; 3; 5;...; 199. Their sum is \(\dfrac{\left(199+1\right).100}{2}=10000\)

 The difference between two sums is \(10100-10000=100\)
