Question

A purse contains RS .310 in the denomination of RS. 10 and RS .50 if the number of RS 10 notes is one more than that RS.50 notes find the number of notes of each denomination​

Answer 1

Step-by-step explanation:

let the 50 rupee notes be x and 10 rupee notes be y

then, 50x + 10y = 310

and , y = x + 1

so, 50x + 10x + 10= 310

60x = 300

x = 5

so y = 5+1= 6

hence 6 10 rupees note and 5 50 rupees notes
