3 moons+1 star equals 29.
All right.
Actually, there are a few numbers that can be hidden behind the moon:
3*8=24 + 1 star (5) = 29
But 1 moon + 1 moon equals 15.
So one moon equals 7.5.
Step-by-step explanation:
Let the present age of father = x years
and the present age of son = y years
according to the first condition
x + y =44 ........(i)
according to the second condition
x+8 = 2(y+8)
or x+ 8 = 2y + 16
or x- 2y = 8 ............(ii)
solve the equation (i) & (ii) we get
x + y =44
x- 2y = 8
••••••••••••••••••••••••
3y = 36
or y = 12
put the value of y in equation (i), we get
x + 12 =44
or x = 32
so the present age of father = x =32 years
and the present age of son = y = 12 years.
