Question

Sunita has some notes of Rs.50 and Rs. 100 amounting to a total of Rs.15,500. If the
total number of notes is 200, then find how many notes of Rs. 50 and Rs.100 each she
hás?

​

Answer 1

Step-by-step explanation:

let the number of ₹50 notes be x and ₹100 be y

according to the question

x+y= 200

x= 200-y (1)

and again

50×x+ 100×y= ₹15,500

Putting the value of x in (2)

We have,

₹50(200-y)+100y= ₹15500

₹10000-₹50y+100y= ₹15500

₹50y= ₹15500-₹10000

y= 5500/50= 110

x = 200-110= 90

Sunita has 90 notes of ₹50 and 110 notes of ₹100
