Question

Rimsha and Nalini’s mother was soaking some moong gram in water, after sometime they both observed that few moong gram seeds started floating on top of the water as shown in the figure given below. Answer the questions based on their observations: (i) Classify the seeds as healthy and unhealthy. Justify your answer with a suitable explanation. (ii) Why it is important to select good quality seeds for sowing?​

• 2x + 3y = 11 \: (eq.\: 1)2x+3y=11(eq.1)
• 2x \: – \: 4y = -24(eq. \: 2)2x–4y=−24(eq.2)
• subtracting \: eq \: 1from \: 2subtractingeq1from2
• 2x \: - \: 4y - (2x + 3y) = -24 - 112x−4y−(2x+3y)=−24−11
• \begin{gathered} = > 2x - 4y - 2x - 3y \\ = - 35 \\ \\ = > \: 7y \: = - 35 \\ \\ y \: = \frac{35}{7} \\ \\ = > y \: = 5\end{gathered}
• =>2x−4y−2x−3y
• =−35
• =>7y=−35
• y=
• 7
• 35
• =>y=5
• \begin{gathered}now, \\ \\for \: the \: value \: of \: x, \\ in \: equation \: 1 \\ putting, \: the \: value \\ of \: y \: \\ 2x + 3y = 11\end{gathered}

• 2x+3y=11
• \begin{gathered} = > 2x \: + 3 \times 5 = 11 \\ \\ (value \: of \: y \: = 5) \\ \\ = > 2x \: + \: 15 \: = 11 \\ \\ = > \: 2x \: = 11 - 15 \\ \\ 2x = - 4 \\ \\ = > x = \frac{4}{2} \\ \\ = > x \:= 2\end{gathered}
