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:
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
