Question

in bag there rare coins of 25p,10p,and 5p ratio of 1:2:3 of the rs.30 is in all then what % of amount is made up by 25p coins​

Answer 1

Explanation:

Take no. of 25p coins be x

No.of 10p coins be 2x

No. of 5p coins be 3x

as, we know 1 rs =100 p

so 30rs=30×100=3000p

so, total amount of 25p coins=25x

Total amount of 10p coins=20x

Total amount of 5p coins=15x

so, 25x+20x+15x=3000

=>60x=3000

=>x=3000÷60

=x=50

so total amount of 25p coins=50×25=1250p=12.5rs

so percentage of amount of 25 p coins=12.5/30×100

≈41.6%(approx.)
