Let's convert the binary numbers to decimal:
(1000)₂ = 1 × 2³ = 8
(0010)₂ = 0 × 2³ + 1 × 2¹ = 2
Now, multiply:
8 × 2 = 16
The phrase "all but 10 died" means that 10 goats are left alive.
A subset is a set whose elements are all contained within another set.

Let's denote Hyder's present age as x.
According to the problem:
(2/3)x + 12 = x + 3
Let's solve for x:
(2/3)x - x = 3 - 12
-(1/3)x = -9
x = 27
