a person has currency notes of denomination rupees 50 and rupees 10 respectively. The ratio of the number of these notes is 3:5. If the total money is rupees 2400. Find the number of notes of each denomination.
Answers
let no. of Rs. 50 notes be 3x and Rs. 10 notes be 5x
A/Q,
=> 50 X 3x + 10 X 5x = 2400
=> 150x + 50x = 2400
=> 200x = 2400
=> x = 12
total no. of Rs. 50 notes = 3 x 12 = 36
total no. of Rs. 10 notes = 5 x 12 = 60
Answer:
36 notes and 60 notes respectively
Step-by-step explanation:
Given, Ratio = 3 : 5
let the value of ration be y, then
Total Sum of Rs. 50 notes : 3y * 50 = 150y Rs.
Total Sum of Rs. 10 notes : 5y * 10 = 50y Rs.
Total sum = Rs. 2400
since, 150y + 50y = 2400
200y = 2400
y = 2400 / 200
y = 12
Therefore, No. of Rs. 50 notes : 3x = 3 * 12 = 36 notes
No. of Rs. 10 notes: 5x = 5 * 12 = 60 notes
