Answer:
1/12
Step-by-step explanation:
1/3 times 1/4 is 1/12
Try this solution:
let the unknown two-digits number be 'xy'.
Then it is possible to write any two-digit number as 10x+y, where x - the tens digit and y - the unit digit.
Using the rule described above the phrase 'the tens digit of a number is twice the units digit' may be written as x=2y.
Using the same rule the phrase 'if the digits are reversed, the new number is 36 is less than the original number' may be written as (10x+y)-(10y+x)=36.
These two equations may be resolved as system of two equations:

Check: the original number is 84, the new number is 48; difference is 84-48=36.
answer: 84
Switch the variable x and y with each other. Then the correct option is B.
<h3>What is inverse of a function?</h3>
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
The function is given below.
f(x) = 3x – 10
Then the inverse function of the f(x) will be
Put y in place of f(x).
x = 3y – 10
3y = x + 10
y = (x + 10) / 3
Switch the variable x and y with each other.
Then the correct option is B.
