Question

- यदि (x + 1) : 8 = 3.75 : 7, तो x का मान है-​

Answer 1

Answer:

$\frac{x + 1}{8} = \frac{3.75}{7} \\\frac{x + 1}{8} = \frac{375}{700} \\ \frac{x + 1}{8} = \frac{15}{28} \\ x + 1 = \frac{15}{28} \times 8 \\ x + 1 = \frac{15}{7} \times 2 \\ x + 1 = \frac{30}{7} \\ x = \frac{30}{7} - 1 = \frac{30 - 7}{7} = \frac{23}{7} = 3 \frac{2}{7}$
