Question

Alex’s age is three times the age of his son Krishna. If the difference of their ages is 11 years, find there present ages. (Hint) use algebra

Answer 1

Answer:

16.5 and 5.5

Step-by-step explanation:

Let Krishna's age be  x

Alex's age = 3x

3x - x = 11

2x = 11

x = 11/2 (multiplication becomes division - transposition)

x = 5.5

Krishna's age  = 5.5

Alex's age = 3x

                 = 3 x 5.5

                 = 16.5

(16.5 - 5.5 = 11)
