Question

a purse contains rupees 50000 in notes of denominations of rupees 500 and Rs 100 respectively if the total number of nodes is 200 find the number of each type of notes

Answer 1

let number of notes of 500 be x

number of notes of 100 be y

so A.T.Q

x+y=200 equation 1

500x+100y=50000

5x+y=500 equation 2

from equation 1

x=200-y equation 3

put value from equation 3 in equation 2

5*(200-y)+y=500

1000-5y+y=500

 -4y=500-1000

-4y=-500    

y=-500/-4

y=125

so x=200-y

x=200-125

x=75

note of 100 are 125 and note of 500 are 75
