Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that 
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information 
As we know that 
Sn = (a1 + a4) ×  n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
 16 = 2a1 + 6
 2a1 = 10
 a1 = 10 ÷ 2 
= 5
So,  a4 = a1 +6 
= 5 +6 
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3 
= 2
So, 
a2 = a1 + d 
= 5 + 2 
= 7
a3 = a2 + d 
= 7 + 2 
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.
