Let Shobo's age be x years. Therefore, his mother's age will be 6x years.

According to the given question,

After 5 year, shobo's age = \( \frac{shobo's\, mother's\,present\,age}{3}\)

x + 5 = \(\frac{6x}{3}\)

x + 5 = 2x

Transposing x to R.H.S, we obtain

5 = 2x - x

5 = x

6x = 6 × 5 = 30

Therefore, the present ages of Shobo and Shobo's mother will be 5 years and 30 years respectively.

Solve the inequations and graph their solutions on a number line – 4 ≤ 4x < 14, x ε N

Solve (\( \dfrac{x}{3}\)) + (\( \dfrac{1}{4}\)) < (\( \dfrac{x}{6}\)) + (\( \dfrac{1}{2}\)), x ε W. Also represent its solution on the number line.

If the replacement set is {-3, -2, -1, 0, 1, 2, 3}, solve the inequation \(\dfrac {(3x – 1) }{2} < 2\). Represent its solution on the number line.

Solve the inequations (\( \dfrac{3}{2}\)) – (\( \dfrac{x}{2}\)) > – 1, x ε N
