Answer 2

Answer:

let there be x 100rs notes and y 25 rs notes

thus

100x + 25 y = 3000 ----(1)

we have

x+y = 63

multiply the above with 100

100 x + 100 y ===> 6300 ----(2)

(2) - (1) ===> 75 y ===> 3300

=====> y = 44

now x = 19

there fore in the purse

there was 19 hundred rs notes and 44 twenty five rs notes
