Question

A purse contains 550 in notes of denominations of 10 and 50. If the number 250 notes is one less than that of 10 notes, then find the number of 50 notes.​

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
