Divit has a total of ₹6000 currency
notes of denomination ₹50,₹100 and ₹200. The proportion of the no. of these notes is 2:3:4. How many notes of each denomination does he have?
Answers
Step-by-step explanation:
Total money = ₹6000
Ratio of ₹50,₹100 and ₹200 = 2:3:4
Let the numbers of ₹50,₹100 and ₹200 = 2x:3x:4x respectively
ATQ, 2x + 3x + 4x = ₹6000
9x = ₹6000
x = ₹6000/9
x = 666.666
Numbers of ₹50 notes = 666.6 × 2
Concept
Since the ratio of the number of notes of 50 Rs, 100 Rs and 200 Rs are given, therefore we will use this ratio to make an equation to find out the proportionality of each type of notes.
Given
The total amount of money is 6000 Rs.
There are only 50 Rs, 100 Rs and 200 Rs notes.
The ratio of the notes is 2:3:4.
Find
We have to calculate the number of notes for each type.
Solution
Since the ratio of the number of the notes is 2:3:4 and let their proportional to x, therefore from the given condition we can write,
(2x*50 Rs)+(3x*100 Rs)+(4x*200Rs)=6000 Rs
Therefore solving the above equation we get,
100x+300x+800x=6000
1200x=6000
x=5
Therefore the number of 50 Rs note = 2x=2*5=10
The number of 100 Rs notes = 3*5=15
The number of 200 Rs notes = 4*5=20
Hence the number of notes of 50 Rs, 100 Rs and 200 Rs are 10, 15 and 20 respectively.
