Question

A number was reduced to 210 by a reduction of 30%. By what percent should it be increased to convert it into 450

Answer 1

Hyy Dude

30% of 210 is

30/100 * 210 =63

Hence the original number must be 210+63=273

Now we want to increase the number from 273 to 450 and find out the percentage required to increase the number.

let x be the percentage of 237=450

x/100 *273 = 450

Therefore,

x=(450*100)/273 = 164.84%
