Let us assume that the number with which Anita has to perform the multiplication is 'x'.
Instead of finding 35x, she calculated 53x.
The difference = 53x - 35x = 18x = 540
Therefore, x = 540/18 = 30
So, the new product = 30 x 53 = 1590.

Given: One multiplier is 35 and the other is 53.
The difference in multipliers = 53 - 35 = 18
The difference in product = 540
Let's assume the original product was P.
New product = Original product + Difference in product
New product = P + 540
We can write the equation using the given multipliers as:
P = 35 * a
P + 540 = 53 * b
where a and b are the other multipliers in the two equations.
We can simplify the above equations as:
a = P/35
b = (P + 540)/53
Substituting the value of a in the second equation, we get:
b = (P/35) + (540/53)
Multiplying both sides by 35*53, we get:
35*53*b = 53*P + 35*540
1875b = 53P + 18900
53P = 1875b - 18900
As P is an integer, 1875b - 18900 must be divisible by 53.
Dividing both sides by 53, we get:
P = (1875b - 18900)/53
Now, we need to find the value of b that satisfies the given conditions.
We know that the difference in multipliers is 18 and the difference in product is 540.
So, we can write:
b - a = 18
53b - 35a = 540
Substituting the value of a in the second equation, we get:
53b - (P/35)*35 = 540
53b - P = 540
Substituting the value of P from earlier, we get:
53b - (1875b - 18900)/53 = 540
Multiplying both sides by 53, we get:
53*53b - (1875b - 18900) = 28620
53*53b - 1875b + 18900 = 28620
2809b = 9520
b = 9520/2809
Substituting the value of b in the equation for P, we get:
P = (1875b - 18900)/53 = (1875*(9520/2809) - 18900)/53 = 1590
Therefore, the new product is 1590.
The difference in multipliers = 53 - 35 = 18
The difference in product = 540
Let's assume the original product was P.
New product = Original product + Difference in product
New product = P + 540
We can write the equation using the given multipliers as:
P = 35 * a
P + 540 = 53 * b
where a and b are the other multipliers in the two equations.
We can simplify the above equations as:
a = P/35
b = (P + 540)/53
Substituting the value of a in the second equation, we get:
b = (P/35) + (540/53)
Multiplying both sides by 35*53, we get:
35*53*b = 53*P + 35*540
1875b = 53P + 18900
53P = 1875b - 18900
As P is an integer, 1875b - 18900 must be divisible by 53.
Dividing both sides by 53, we get:
P = (1875b - 18900)/53
Now, we need to find the value of b that satisfies the given conditions.
We know that the difference in multipliers is 18 and the difference in product is 540.
So, we can write:
b - a = 18
53b - 35a = 540
Substituting the value of a in the second equation, we get:
53b - (P/35)*35 = 540
53b - P = 540
Substituting the value of P from earlier, we get:
53b - (1875b - 18900)/53 = 540
Multiplying both sides by 53, we get:
53*53b - (1875b - 18900) = 28620
53*53b - 1875b + 18900 = 28620
2809b = 9520
b = 9520/2809
Substituting the value of b in the equation for P, we get:
P = (1875b - 18900)/53 = (1875*(9520/2809) - 18900)/53 = 1590
Therefore, the new product is 1590.

The product went up by +540
right number that has to be taken was 35.
instead they took 53, so extra he taken is 53-35= 18.
from here we can find the 2nd number of the multiplication
i.e 540/18 = 30.
now that the one number is 30.
and the number taken now instead of 35 is 53.
so, the present calculation would be 53*30= 1590.
