Question

a purse contains Rs 550 in notes of denominators of rupees 10 and rupees 50 if the number of rupees 50 notes is one less than that of rupees 10, notes then find the number of 50 note.​

Answer 1

Answer:

Total amount in a purse= 550

Let number of notes of 10 =x

The number of notes of 50= x-1

According to the condition,

x×10+(x−1)×50=550

⟹10x+50x−50=550

⟹60x=550+50=600

⟹x=10

50 rupees notes= 10-1= 9

Answer 2

Step-by-step explanation:

since total money us 550

let 50 notes by x and 10 notes be y

y=x+1

50x+10y=550

50x+10(x+1)=550

50x+10x+10=550

60x=540

×=9

y=10
