The sum of clyde and wendys age is 64 in four years wendy will be three times as old as clyde how old are they now
~~~~~~~~~~~~~~~~
Read attentively:
In 4 years, Wendy will be three times as old as Clyde and the sum of their ages will be 64 + 4 + 4 = 72 years.
So, let in 4 years, Clyde's age will be x; then Wendy's age will be 3x, and
x + 3x = 72
4x = 72
x = 72/4 = 18.
Thus in 4 years Clyde's age will be 18 years, while Wendy's age will be 3*18 = 54 years.
Hence, now Clyde is 18-4 = 14 years old; Wendy is 54-4 = 50 years old. ANSWER
