Question : 5 of 100

Marks: +1, -0

\frac{28\times5-15\times6}{7^2+\sqrt{256}+(13)^2}

= ?

Solution:

Concept:

Simplify the numerator and denominator separately, then reduce the resulting fraction.

Explanation:

Numerator

= 28 \times 5 - 15 \times 6

= 140 - 90

= 50

Denominator

= 7^2 + \sqrt{256} + (13)^2

= 49 + 16 + 169

= 234

So, the expression becomes

\frac{50}{234}

Divide numerator and denominator by

2

= \frac{25}{117}

Answer:

\frac{25}{117}

, which matches option C.
