Answer 1

• Sokhem: 30
• Chanda: 18

Explanation:

(c+6) +2c = 60

3c = 54 . . . . . . . . subtract 6, collect terms

c = 18 . . . . . . . . . . divide by 3

Chanda is 18, Sokhem is 30.

In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
