• A. 43:72
• B. 49:76
• C. 43:76
• D. 49:72
• E. None of these

Answer 1

The correct option is E

None of these

Total Number = 11200
$\begin{array}{cc}Store& Nokia/Samsung\\ P& 4:3\\ Q& 3:1\\ R& 5:4\\ S& 7:6\\ T& 1:4\\ U& 11:10\end{array}$
Number of Nokia phones sold by store S = 1688(approx)
Thetotal number of Samsung phones sold by store T $=\frac{4}{5}\times \frac{20}{100}\times 11200=1792$
The total number of Samsung phones sold by store U
$=\frac{10}{21}\times \frac{12}{100}\times 11200=640$
$\therefore$ Required ratio
= 1688 : (1792 + 640)
= 166 : 2432 = 211 : 304
