Let the no.of rs 1 coins he has be x
The no. Of rs 2 coins he has=50-x
Amount of rs 1 coin he has=1(x)
Amount of rs 2 coin he has=2(50-x)
Total amount he has=₹75
So,x+2(50-x)=75
x+100-2x=75
-x=75-100
-x=-25
So x=25
No of rs 1 coin he has=25
No if rs 2coin he has=25
The no. Of rs 2 coins he has=50-x
Amount of rs 1 coin he has=1(x)
Amount of rs 2 coin he has=2(50-x)
Total amount he has=₹75
So,x+2(50-x)=75
x+100-2x=75
-x=75-100
-x=-25
So x=25
No of rs 1 coin he has=25
No if rs 2coin he has=25
