Question

A purse contains rs.310 in the denomination of Rs.10 and rs.50. if the number of rs.19 notes is one more than that of rs.50, Find the number of notes of each denomination.

Answer 1

Step-by-step explanation:

Total amount in purse is 310rs

let the numbers of 50rs note be = X

so number of 10 rs note be =X+1

Now the equation becomes

10×(x+1) + 50×(x) =310

10x + 10 + 50x =310

60x= 310-10

60x = 300

x= 300/60

x = 5

so x is the number of 50 rs note that is 5 notes

and 10 rupee note is 1 more than 50 rupees note that is x+1 = 6

50rs note = 5 ie 250

10rs note = 6 ie 60
