Answer 1

Answer:

6 ₹100 notes, 18 ₹50 notes , 54 ₹20 notes, 162 ₹10 notes

Step-by-step explanation:

let number of ₹100 notes be x

therefore, number of ₹50 notes is 3x

similarly number of ₹20 notes is 9x and number of ₹10 notes is 27x

100*x + 50*3x +20 * 9x + 10 * 27x = 4200

100x + 150x + 180x +270x = 4200

700x = 4200

x = 6

therefore there are 6 ₹100 notes, 18 ₹50 notes , 54 ₹20 notes, 162 ₹10 notes
