Answer:−
Laxmi has 2000 notes of Rs. 100 notes, 3000 notes of Rs. 50 and 5000 notes of Rs. 10.
\mathfrak{\large{\underline{\underline{Explanation :-}}}}
Explanation:−
Given :
Total cash with Laxmi = Rs. 4,00,000
Ratio of Rs. 100, Rs. 50 and Rs. 10 notes = 2 : 3 : 5
To Find :
Notes of each denomination with Laxmi
Solution :
◆ \textbf{\small{\underline{Consider -}}}
Consider -
Number of Rs. 100 notes as 2x
Number of Rs. 50 notes as 3x
Number of Rs. 10 notes as 5x
\boxed{\sf{100(2x)+50(3x)+10(5x)=4,00,000}}
100(2x)+50(3x)+10(5x)=4,00,000
\tt{\longrightarrow} \: 100(2x)+50(3x)+10(5x)=400000⟶100(2x)+50(3x)+10(5x)=400000
\tt{\longrightarrow} \: 200x+150x+50x=400000⟶200x+150x+50x=400000
\tt{\longrightarrow} \: 200x+200x=400000⟶200x+200x=400000
\tt{\longrightarrow} \: 400x=400000⟶400x=400000
\tt{\longrightarrow} \:x = \dfrac{400000}{400}⟶x=
400
400000
\tt{\longrightarrow} \:x = 100⟶x=100
★ Value of 2x
\tt{\longrightarrow} \:2 \times 1000⟶2×1000
\tt{\longrightarrow} \:2000⟶2000
Rs. 100 notes = 2000
★ Value of 3x
\tt{\longrightarrow} \:3 \times 1000⟶3×1000
\tt{\longrightarrow} \:3000⟶3000
Rs. 50 notes = 3000
★ Value of 5x
\tt{\longrightarrow} \:5 \times 1000⟶5×1000
\tt{\longrightarrow} \:5000⟶5000
Rs. 10 notes = 5000
\therefore∴ Laxmi has 2000 notes of Rs. 100 notes, 3000 notes of Rs. 50 and 5000 notes of Rs. 10.
