more notes of rupee 50 than rupee 20 if the total amount collect
is rupee1100, how many notes of each kind does he have ?
​

Answer 1

Answer:

Let the number of Rs. 50 notes and Rs. 20 notes be 5x and 3x respectively.

As she ahs 25 notes in total.

The number of Rs. 10 notes = 25 - (3x + 5x) = 25 - 8x

The amount she has

Total money = 590

3x × 50 + 5x × 20 + 10 (25 - 8x) = 590

150x + 100x + 250 - 80x = 590

170x = 340

x = 2

The number of Rs. 50 notes = 3 × 2 = 6

The number of Rs. 20 notes = 5 × 2 = 10

The number of Rs. 10 notes = 25 - 8 × 2 = 9

Answer 2

Step-by-step explanation:

Let the number of 20 notes be x

Value of 20 notes = ₹20x

Given, 50 notes are four times than 20 notes.

So number of 50 notes = 4x

Value of 50notes = ₹50 * 4

= ₹200x

Now, Given that the sum of 50 notes and 20 notes is 1100.

So,

₹200x + ₹20x = ₹1100

= ₹220x = ₹1100

x = 5

She has 5 notes of ₹20

and 20 notes of ₹50
