A person had to multiply two numbers. Instead of multiplying by 35, he multiplied by 53and the product went up by 540. What was the raised product?

a) 780

b) 1040

c) 1590

d) 1720

• 53*x-35*x=540
  x=30
  Raised Product=53*30=>1590

• instead we can write (53-35)x=540
  x=30
  so 53*30=1590 it is a easy step y r using such big steps

• assume first no is x,
  product of x and 35= p
  
  product after x multiplied by 35 is p= 35*x
  but he multiplied by 53 instead of 35 product raised by 540 which is equal to p+540
  so
  x multiplied by 53 = 53*x which is equal to p+540 (p=35*x)
  53*x=p+540;
  53*x=35*x+540 (putting value of p=35*x);
  53*x-35*x=540;
  (53-35)*x=540;
  18*x=540;
  x=540/18;
  x=30;
  now we can calculate raised product
  which is = 53*x
  =53*30 (putting value of x)
  =1590
  ANSWER= 1590

• Let us assume the number to be 'n'
  When we perform the multiplication of the number 'n' by 35 we get n*35 =p (say)
  But by mistake the person does multiplication of number 'n' by 53.as per data..the product is more by 540.
  We get , n*53 = p +540.
  now we have ( n*53) -(n*35) =(p+540)-(p)
  (n*53)-(n*35) = 540
  Now , taking n common.we get
  n (53-35) =540
  n (18)=540
  Therefore, n=30.
  The raised product is nothing but 30*53=1590.
  Option c) 1590

• 1590
  solve the eq ,x(53-35)=540
  u will get x,,now multply x with 53.

• Let the multiple of a number be x.
  now from the give question, 53*x - 35*x = 540
  then 18 * x= 540
  now x= 30.
  The raised product is given by 53*30 = 1590.
  .
  . . Ans is 1590.
