Question

Two number are 10% and25% more then third number what percentage is the first of the second

Answer 1

Answer:  88%

Step-by-step explanation:

Let “x”, “y”, and “z” be the three numbers which are related to each other as given in the problem question.

Then, “x” is 10% more than “z” means, x = z + 10% of z.

That is, x = z + (z × 10/100).

That is, x = z + 0.1z = (1 + 0.1) × z = 1.1 × z.

Then, “y” is 25% more than “z” means, y = z + 25% of z.

That is, y = z + (z × 25/100) = (1 + 0.25) × z = 1.25 × z.

Then, part of “x” upon “y” means,

x/y = (1.1 × z) / (1.25 × z) = 110/125 = (22 × 5) / (25 × 5) = 22/25 = (22/25) × 100% = 22 × (100/25)% = 22 × 4% = 88%.

That is, x = 88% of y
