Let the number of 5 notes be = x

Total no. of notes is =90

Hence the number of rs. 10 note be (90-x)

Total sum of money = rs. 500

.

. . 5x +10 (90-x)=500

➡️ 5x+900-10x=500

➡️ 5x = 500-900

➡️ 5x= -400

➡️ x= -400÷-5 = 80

Hence there are 80 notes of rs. 5

Number of rs. 10 notes =90-80==10

Hence there are 10 notes of rs. 10.
