If \(\frac{3}{x} = 2\) and \(\frac{y}{4} = 3\), then \(\frac{{3 + y}}{{x + 4}}\) = ?
Solution
Correct Answer: Option A
Solution:
যদি \(\frac{3}{x} = 2\) এবং \(\frac{y}{4} = 3\) হয় তবে \(\frac{{3 + y}}{{x + 4}}\) = কত ?
দেয়া আছে, \(\frac{3}{x} = 2\)
=> 2x = 3
x = \(\frac{3}{2}\)
আবার, \(\frac{y}{4} = 3\) y = 12
প্রদত্তরাশিমালা = \(\frac{{3 + y}}{{4 + x}} = \frac{{3 + 12}}{{4 + \frac{3}{2}}} = \frac{{15}}{{\frac{{8 + 3}}{2}}} = \frac{{15}}{{\frac{{11}}{2}}} = 15 \times \frac{2}{{11}} = \frac{{30}}{{11}}\)
