Question

there are 800 coins in a bag valued as re 315.if the coins are of 25 paise and 50 paise denomination, find the number of coins of each denomination

Answer 1

let 25 paise coins be x in number.
number of 50 paisa coins = 800-x
so,
According to question (ATQ)
25(x)+50(800-x)=31500
25x+40000-50x=31500
40000-25x=31500
25x=40000-31500
25x=8500
x=8500/25
x=340
so,
25 paisa coins = 340
50 paisa coins = 800-340 = 460

Answer 2

Step-by-step explanation:

25x+50(800-x)=31500

25x+40000-50x=31500

40000-25x=31500

25x=40000-31500=8500

x=8500/25=340

25 paise coins=340

50paise coins=800-340=460
