4750

Answer:- 1

Explanation:-

Solution:

\begin{aligned} 78 % of 750 + 34 % of x = 30 % of 2630 \\ O r, {\frac{(78 \times 750)}{100}} + \frac{34 x}{100} = (30 \times 2630) \times 100 \\ O r, 78 \times 750 + 34 x = 30 \times 2630 \\ O r, 34 x = 78900 - 58500 \\ O r, x = \frac{20400}{34} \\ Hence, x = 600 \end{aligned}

$\eqalign{ & 78\% \,{\text{of}}\,750 + 34\% \,{\text{of}}\,x = 30\% \,{\text{of}}\,2630 \cr & Or,\,\left\{ {\frac{{\left( {78 \times 750} \right)}}{{100}}} \right\} + \frac{{34x}}{{100}} = \left( {30 \times 2630} \right) \times 100 \cr & Or,\,78 \times 750 + 34x = 30 \times 2630 \cr & Or,34x = 78900 - 58500 \cr & Or,x = \frac{{20400}}{{34}} \cr & {\text{Hence}},x = 600 \cr}$
