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

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.
