Question

The sum of 5% of a number and 4% of a second number is 2/3 of the sum of 6% of the first number and 8% of the second number is the ratio of the first number to the second number?​

Answer 1

Let the number A is x and number B is y

Then 5% of a is

5/100x=0.05x and

4% of number B is

4/100x=0.04y

Then 6% of a is

6/100x=0.06x and

8% of number B is

8/100x=0.08y

As per given in question

∴0.05x+0.04y= 3/2

(0.06x+0.08y)

⇒0.15x+0.12y=0.12x+0.16y

⇒0.15x−0.12x=0.16y−0.12y

⇒0.03x=0.04y

⇒ x/y = 4/3.
