Question

The sum of three numbers is 133

. The third number is 4

 times the second. The first number is 7

 more than the second.What are the numbers? 

Answer 1

F + S + T =133

T=4S

F= 7+S

7+S + S + 4S = 133

6S = 133-7 = 126

S = 126/6 = 21= the second number

T = 4S = 4(21) = 84 = the third number

F = 7+S = 28 = the first number

28 +21 + 84 = 133
