Answer:
Sara is 27 years old and Ahmed is 31 years old.
Explanation:
Sara was 22 years old before.
Ahmed was 26 years old before.
5 years before= 5+5=10
So, minus five from both to make 10.
Now add five plus five to make 10 to find their current age by subtracting 4 years from Ahmed's age.
sara=s
ahmed = s+4 (4 years older than Sara)
s-5 + (s+4)-5 = 48
2s -6 = 48
2s = 54
s=27
SARA is 27 AHMED is 31
5 years ago:
SARA WAS 22 AHMED WAS 26
22+26 =48
