notes is 2:3:5. The total cash with Lakshmi is 4,00,000. How many notes of each denomination does she have?​

Answer 1

Answer:Answer:

Let 100 rupee be 100x

50 rupee be50x

10 rupee be 10x

Now,

Value of 100 rupee 50 rupee and 10 rupee be 2*100x ,3*50x ,5*10x

= 200x+150x+50x= 400000

400x=400000

X= 1000

No of 100 rupee notes=200*1000=200000

No of 50 rupee notes =150*1000=150000

No of 10 rupee coin = 50*1000=50000

Step-by-step explanation:

Answer 2

❍Given

Ratio of all the Notes 100, 50, 10= 2:3:5

Total Cash=4,00,000

❍To Assume

How many notes of each denomination does she have?

❍Solution

Let the no. be $\color{orange}{X}$

$Notes \: \: of \: \: ₹ \: 100=2x \\ Notes \: \: of \: \:₹ \: 50=3x \\ Notes \: \: of \: \: ₹ \: 10=5x$

Total number of

$100 = 2x \times 100 = 200x \\ 50 = 3x \times 50 = 150x \\ 10 = 5x \times 10 = 50x$

Total Cash:-₹4,00,000

200x + 150x + 50x =4,00,000

$\color{hotpink}{200x + 150x + 50x}$=4,00,000

$\color{hotpink}{400}$x=$\color{crimson}{4,00,000}$

X = $\color{hotpink}{ \frac{400000}{400}}$

X = $\color{crimson}{1000}$

• Notes of ₹100=2x=2(1000)= ₹2000
• Notes of ₹50=3x=3(1000)= ₹3000
• Notes of ₹10=5x=5(1000)= ₹5000

Verification :-₹2000 + ₹3000 + ₹5000 = ₹4,00,000

∴ Lakshmi has Notes of ₹100 = ₹2000

Notes of ₹50 = ₹3000

Notes of ₹10 = ₹5000
