Question

if the price of pencil decreased by 16 2/3% and the 

decrease is Rs.3 find out of the new pencil price

Answer 1

Call the original pencil price x. Then we can say "3 is 16 2/3% of x." So, to write that as an equation:

 

3 = 0.16666667x

300 = (16 2/3)x

18 = x

 

So, the original pencil price was Rs.18. That means the new pencil price is 18 - 3 = Rs.15.
