lakshmi is a chashier in a bank. shae has currancy notes of denomination Rs100,Rs50 and Rs 10 ,respectively.the ratio of the number of these notes is 2:3:5. the total cash with lakshmi is 400000. how many notes of each denomination does she have?
let number of 100 notes = 2x , number of rs 50 notes =3x and number of rs 10 notes = 5x , therefore 100*2x +50*3x +10*5x = 4 00 000 => 200x +140x+50x = 4 00 000 => 400x =400000 =>x=400000/400 => x= 1000 ... therefore number of rs 100 notes = 2x = 2*1000 = 2000 and number of Rs 50 notes = 3x = 3*1000 =3000 and Number of Rs 10 notes = 5x=5*1000 =5000 . hope this helps you.
