Answer 2

Answer:

Given,

Value of m/n = 4/3.

Value of r/t= 9/14.

To Find,

The value of 3mr- nt / 4nt- 7mr.

Solution,

We can simply find the value of 3mr- nt / 4nt- 7mr by taking common and substituting some values.

Let us take (nt) common from both, the numerator and the denominator.

We get, nt (3mr/nt-1)/ nt (4- 7mr/nt).

We can cancel "nt" and then we get, (3mr/nt -1 )/ ( 4- 7mr/nt).

Since we know the value of m/n = 4/3 and r/t= 9/14.

We can substitute them in our equation.

We get, (3×4/3×9/14 - 1)/ ( 4- 7×4/3×9/14).

Solving we get, -11/14.

Hence, option(b) is the correct choice.
