Question

A wallet contains ₹4080 in notes in denominations of ₹10, ₹20, ₹50, and ₹100 in the ratio of 1 : 3 : 5 : 7 respectively. How much money do the 20 and 50 rupee notes sum up together?

Answer 1

In a purse there are 20 rupee notes 10 rupee notes and 50 rupee notes.

Let the number of ₹10 note be 'x'.

Now Given:

The number of 50 rupee notes exceeds 2 times the number of 10 rupee note by 1.

Hence we can say that;

the number of ₹50 note =

Also;

The number of 20 rupee notes are 5 less than the number of 10 rupee notes.

Hence we can say that;

the number of ₹20 note =

Again Given:

Total Value in purse = ₹860

Value of ₹10 notes =

Value of ₹20 notes =

Value of ₹50 notes =

Now we know that;

Total Value in purse is sum of Value of ₹10 notes and Value of ₹20 notes and Value of ₹50 notes.

framing in equation form we get;

Adding both side by 50 using Addition property of equality we get;

Now Dividing both side by 130 using Division property of equality we get;

Number of ₹10 notes = 7

Number of ₹20 notes =

Number of ₹20 notes =

Hence There are 7 numbers of ₹10 notes, 2 numbers of ₹20 notes and 15 numbers of ₹50 notes in the purse.

Answer 2

Answer:

Rs1800

Step-by-step explanation:

let the number of notes per denomination be x

we know

x+5x+3x+7x=4080

16x=4080

x=4080/16

x=225

Now value of respective notes are:-

Rs10=1(225)=225 (sub 225 instead of x)

Rs20=3(225)=675

Rs50=5(225)=1125

Rs100=7(225)=1575

The total is 4080

part2

sum of rs20 plus sum of rs50

675+1125=1800

Rs1800
