Question

A sum of rs 1000 is in the form of denomination of rs10 and 50rs.if the total number of notes is 60, find the number of notes of each type.

Answer 1

let 10rs. note =A,
50rs. note=B,

then
A+B=60......eq(1),

10A+50B=1000,

A+5B=100.......eq(2),

eq(2) - eq(1), we get

5B-B=100-60,

4B=40,

B=10,

then
A+10=60,

A=50
