Question

What is the approximate value in the following equation?
84.95% of 280 + √? = 253.001

Answer 1

Given: The term 84.95% of 280 + √? = 253.001

To find: The value of ?

Solution:

• We have given the term 84.95% of 280 + √? = 253.001

• Let ? be x, then:

                   84.95% of 280 + √x = 253.001

• Assume 253.001 = 253

• Solving this:

                   (84.95/100) x 280 + √x = 253

                   (84.95/10) x 28 + √x = 253

                   2378.6/10 + √x = 253

                   √x = 253 - 237.86

                   √x = 15.14

• Squaring on both sides, we get:

                   x = 15.14²

                   x = 229.2196

Answer:

                   So the value of ? is 229.2196.
