Question

a sum of ₹530 is in the form of denominations of ₹5 and ₹10. if the total number of notes be 79, find the number of each type of notes.​

Answer 1

Step-by-step explanation:

Hey mate here is your answer

Let no. of Rs 5 notes be x and no. of Rs 10 notes be y

Total number of notes is 79⇒ x + y = 79 ........(1)

Total amount = 530

5x + 10y = 530  ...(2)

Multiply equation (1) by 10

10x + 10y = 790  .....(3)

Subtract eqution (2) from equation (3)

10x + 10y = 790

5x + 10y = 530

----------------------

5x = 260

----------------------

x = 52

y = 79-52=27

No. of Rs 5 notes = 52

No. of Rs 10 notes = 27

hope it will help you❤❤
