Question

An alloy weighing 50 gm contains 40 gm of silver.A piece of 30 gm of alloy is cut from it.find the weight of silver present in the remaining piece of alloy??​

Answer 1

Answer:

16 gram silver is remaining in the alloy

Step-by-step explanation:

50 gram alloy in that 40 gram silver

means in 100 percent 80 percent is silver

so a piece of 30 gram is cut so it means 60 percent is cut

40 (silver )+10 graph

40 g =80%(the percent of silver )

80÷100=0.8 (the percent of silver )

60%-100%

=36%

36%÷2 (the amount of silver in gram that is remaining )

=16 gram is remaining

=16 gram
