Now, 90 unit = 477 Tk.

390" = 2067 Tk.

Then, the original Prices of the two houses=2067 Tk. (Ans)

Here, Let Present age of Father be F and Son be S

Atq, (F - 20) = 4(S - 20)

So, F - 4S =-60....(i)

Again, (F + 4) = 2(S + 4)

So, F = 2S + 4 (ii)

From Equation (i) and (ii) we Get,

2S + 4 - 4S = - 60

So,  S=642=32 Years

And, F = 2S + 4 = 2 × 32 + 4 = 68 years

So, Present age of father=68 Years (Ans)
