5 pens and 6 pencils together cost Rs 9 and 3 pens and 2 pencils cost Rs 5. Find the cost of 1 pen and 1 pencil.

Correct option is B) Q

Correct option is (D) Rs \(18\frac{3}{4}\) \(\because\) Cost of \(5\frac{2}{5}\) litres of milk = Rs \(101\frac{1}{4}\)  \(\Rightarrow\) Cost of \(\frac{27}{5}\) litres of milk = Rs \(\frac{405}4\) \(\therefore\) Cost of 1 litres of milk = Rs \((\frac{405}4\div\frac{27}5)\) = Rs \((\frac{405}4\times\frac5{27})\) = Rs \((\frac{45}4\times\frac5{3})\) = Rs \((\frac{15\times5}4)\) = Rs \(\frac{75}4\) = Rs \(\frac{18\times4+3}4\) = Rs \((18+\frac34)\) = Rs \(18\frac{3}{4}\).
