Let Ramana's age 8 years ago be x years and mother's age 8 years ago be 5x

2(x + 16) = 5x + 16

2x + 32 = 5x + 16

3x = 16 

  years

Hence, Present age of Ramana =  years

least cost price      = 200*8 = 1600
greatest sold price = 425 * 8 = 3400
profit required = 3400- 1600 = 1800

$$\begin{gathered} 1936 + 529 = ?2 + 256 \\ 2465 = ?2 + 256 \\ ?2 = 2465 - 256 \\ ?2 = 2209 \\ ?=47 \end{gathered}$$
