The sum of the ages of Farhan and his cousin is 38. Seven years ago, Farhan was thrice as old as his cousin. Find Farhan's present age.

25 and 13

Step-by-step explanation:

sum of ages of Farhan and his cousin = 38

7 years ago Farhan thrice of his cousin = 3:1

7 year ago the sum of their ages = 38-14 = 24( 7 years for each)

3:1 = 4 units = 24

1 unit =6

ages of Farhan and his cousin 7 years ago  = 6*3= 18 and 6*1 = 6

so the present age of Farhan = 18+7 = 25 and his cousin 6+7 = 13

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
