Question

plz solve it fast ....

Answer 1

total value of these coin= 300
let X be the total coin of 50/100

then no.of 5coin =150-x
according to question
50/100×x+5(150-x)=300
X/2+750-5x=300
X/2-5x=300
x-10x/2=-450
150--9x/2=-450
-9x=-450×2
-9x=-900
X=-900/-9x=100
so, total coin of 50 paise=100
total coin of 5coin=150-100
=50coin
