If three numbers are added in pairs, the sums equal 10, 19 and 21. Find the numbers
Select the correct option
A) 6, 4, 15  B) 7, 8, 6  C) 5, 15, 45  D) 12, 8, 13  E) 10, 15, 20
Let the numbers be x, y and z. Then,   x+ y = 10 ...(i) y + z = 19 ...(ii) x + z = 21 …(iii)   Adding (i) ,(ii) and (iii), we get: 2(x + y + z ) = 50 or (x + y + z) = 25.   Thus, x= (25 - 19)=

<output>4</output>
4; z= (25 - 10)=

<output>15</output>
15.   Hence, the required numbers are 6, 4 and 15.   6, 4, 15nswer 6, 4, 15)6, 4, 15
