Answer:
Answer:−
Rounak had 13 pens with him and Rahul had 27 pens.
\mathfrak{\large{\underline{\underline{Explanation :-}}}}
Explanation:−
\text{\underline{\underline{\purple{Given :}}}}
Given :
Rounak had = 25
Rahul had = 25 pens
Rounak gave 12 pens to Rahul
\text{\underline{\underline{\purple{To Find :}}}}
To Find :
Number of Pens left with Rahul and Rounak.
\text{\underline{\underline{\purple{Solution :}}}}
Solution :
Rounak had 25 pens, he gave 12 pens to Rahul. To get the pens left with Rounak We need to subtract 12 from 25.
\longrightarrow⟶ 25 - 12
\longrightarrow⟶ 13
Rounak had 13 pens with him.
As 12 pens were given to Rahul, add 12 to the Number of Pens with Rahul.
\longrightarrow⟶ 25 + 12
\longrightarrow⟶ 37
Rahul had 37 pens.
\therefore∴ Rounak had 13 pens with him and Rahul had 27 pens.
