Question

I have 50 rupees in the form of 25 paise coins and 50 paise coins the number of 25 paise coins is three times the number of 50 paise coins a number of 50 paise coins​

Answer 1

Step-by-step explanation:

let the number of 50 paise coins be x

let the number of 25 paise coins be y

Given

$y = 3x$

also since total number value is ₹50

$0.5x + .25y = 50$

using eqn 1 in 2

$.5x + .25(3x) = 50 \\ .5x + .75x = 50 \\ 1.25x = 50 \\ x = \frac{50}{1.25} = 40$

Hence no of 50 paise coins is 40

and number of 25 paise coins is 40*3=120
