thank you

Step-by-step explanation:

Let the first number be X

Let the second number be Y

X= 10% of Z plus Z

Y= 25% of Z plus Z

Where Z is the third number.

X/Y = ( 10 % of Z plus Z) /( 25 % of Z plus Z)

X/Y = ( 1 +0.1)/ ( 1 +0.25)= 1.1/1.25 = 0.88

= 88 per cent.

Answer 2

Solutioɳ:

Let the third number be 100

the first number = 100 + 10 % of 100 = 110

the second number = 100 + 25 % of 100 = 125

the first no. as the percent of the second

110/125 × 100 %

88 %
