Q. The Difference between 42 % of a Number and 28% of Same Number is 210. What is the 59% of that Number ?

Option
a) 630
b) 885
c) 420
d) 900
e) None of these

• (42x / 100) - (28x / 10) = 210
  => x = 1500
  
  => 59x / 100 = 885

• mean 14%=210
  1%=15
  59%=59*15=885

• Difference = 42% - 28%=14%
  
  14% of a number =210
  so, Number=(210*100)/14=1500
  59% of 1500=885
  b is the right answer.

• 885
  210*0.59/(0.42-0.28) =885

• Let No. be x
  so,
  (x*42% - x*28%)= 210,
  x= 1500
  1500*59% = 885

• 42%x-28%x=210
  14%x=210
  x=15000
  59% 15000=885

• 42% of x-28% of x=210,
  14% of x=210,
  x=210/14%=1500,
  59% of x=59% of 1500=885

• let number is x
  (x*(42/100))-(x*(28/100))=210
  =>(42x/100-28x/100)=210
  =>14x=21000
  =>x=21000/14=1500
  number is=1500
  therefore,150*(59/100)=885

• 42/100*x-28/100*x=210
  
  14x=21000
  x=1500
  required number is 1500. 59% of that number is 59*1500/100
  
  answer is 885

• the given number is x and apply formula for all given answers
  so x*59/100=885
  59x=885*100
  x=88500/59
  x=1500 and 42% of 1500 is 630 and 28% of 1500 is 420 the difference between two numbers is 210. so the ans is 885

• b is correct....reason 0.42x-0.28x=210-->x=1500, so 1500*0.59=885.
