25+95=120 25(notes on)=95(no notes on)=120 total
Let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
the greatest common multiple of 24 and 60 is 12
Using PEMDAS, 12-5 is 7. 7^2 is 49. 49+22=71. 71-3=68.
