Answer:

42% of 4000 = x% of 1680

or, 42 /100 * 4000 = x / 100 * 1680

or, 42 * 40 = x * 16.8

or, x = 42*40 / 16.8

---> x = 100 %

So, 4 is the correct answer.

Given,

42% of 4000 = x% of 1680

To find,

The value of x.

Solution,

The value of x will be 100.

We can easily solve this problem by following the given steps.

According to the question,

42% of 4000 = x% of 1680

Removing the sign of percentage,

42×4000/100 = x×1680/100

Dividing 100 by 100, we get

42×4000 = x × 1680

Changing the sides,

x × 1680 = 42×4000

x = (42×4000)/1680 [1680 was in the multiplication on the left-hand side. So, it is in the division on the right-hand side.]

Dividing 4000 and 1680 by 40,

x = 42×100/42

x = 100

Hence, the value of x will be 100.
