Question

4. A purse contain Rs 2500 in notes of denominations of 100 and 50. If the number of
100 rupee notes is one more than that of 50 rupee notes, find the number of notes of
each denomination.​

Answer 1

let 50 rupees notes be ₩

so number of 100 rupees notes = ₩+1

₩(50)+(₩+1)(100)=2500

50₩+100₩+100=2500

150₩=2400

₩=16

so 50 rupees notes=16

and 100 rupees notes=17
