Question

in a bag there are 175 notes of Rs. 5 and Rs. 10 notes. if the total value is Rs 1000 find the number of each types of notes​

Answer 1

Step-by-step explanation:

Let the note of 5 rupees be X and of 10 rupees be y

according to the question :-

5x+10y = 1000. equation 1st

X+y = 175 equation 2nd

=> X = 175-y

putting the value of x in equation 1st

5x+10y = 1000

5(175-y) + 10y = 1000

875-5y+10y = 1000

5y = 125

y = 25

putting the value of y in equation 2nd

X+y = 175

X+25 = 175

X = 150

therefore the number of notes of 5 rupees = X = 150 notes

and the number of notes of 10 rupees = y = 25.

Answer 2

=5x=750

=x=150

hence, 5 rupee note=150 &

10 rupee note=25 i.e. the answers
