Answer 1

Explanation:

Given :-

Manoj scored twice the runs of Rahul.

Rahul's score 30.

⇝To Find :-

What is the score of Manoj .

⇝Solution :-

{\red{✧}}{\underline{\bf{ Let :}}}✧

Let:

{\large{\purple{\rightarrowtail}}{\bf{Score \: of \: Rahul = 30 \: runs}}}↣ScoreofRahul=30runs

{\large{\purple{\rightarrowtail}}{\bf{Score \: of \: Manoj = x \: runs}}}↣ScoreofManoj=xruns

{\large{\purple{\rightarrowtail}}{\bf{Score \: of \: Manoj = 2x \: runs}}}↣ScoreofManoj=2xruns

{\red{✧}}{\underline{\bf{ Finding \: Age \: of \: manoj :}}}✧

FindingAgeofmanoj:

1. {\large{:{\longmapsto{\bf{ Runs \: of \: Manoj = 2x(runs \: of \: rahul)}}}}}:⟼RunsofManoj=2x(runsofrahul)

1. {\large{:{\longmapsto{\bf{ \: \: \: \: \: \: \: \: \: \: \: \: 2x }}}}}:⟼2x

1. {\large{:{\longmapsto{\bf{ \: \: \: \: \: \: \: \: \: \: \: \: 2 \times 30 }}}}}:⟼2×30

1. {\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{60 \: Runs}}}}}}}}}:⟼
2. 60Runs

1. {\red{✧}}{\underline{\bf{ Therefore:}}}✧

Therefore:

• {\large{\blue{\twoheadrightarrow{\red{\bf{Runs {\small_{(Manoj)}} = 60 \: Runs}}}}}}↠Runs
• (Manoj)

• =60Runs

Answer 2

Germination occurs when a new plant grows out from a seed. ... Water allows the seed to swell up and all the chemical reactions involved in the growth of the embryo to take place. Oxygen is needed for aerobic respiration which provides the energy the embryo needs to carry out cell division and grow.
