Question

If 90% x is 315km than what is the value of x

Answer 1

90% x =315
90/100× x =315
90x/100 = 315
X = 315×100/90
= 350

Answer 2

The value of x is 350.

• A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The word "percent" is used to symbolise it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.
• We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.
• The original number is subtracted from the new number, divided by the original number, then multiplied by 100 to get the % increase.

Here, according to the given information, we are given that,

90% $.x = 315$

Or, $\frac{90x}{100} = 315$

Or, $\frac{9x}{10} =315$

Or, $x = 350.$

Hence, the value of x is 350.
