Question

Three numbers have a mean of 35. The second number is seven more than three times the first number and the third number is two less than six times the first number. What is the value of the third number?

Answer 1

Answer:58

Explanation:

35×3=x+3x+7+6x−2

105=10x+5

10x=100

x=10

Third number=6x−2

Third number=6×10−2

Third number=60−2

Third number=58
