The following pie-chart shows the marks scored by a students in different subjects - viz. Physics (ph), Chemistry (Ch), Mathematics (M), Social Science (SS) and English (E) in an examination. Assuming that total marks obtained for the examination is 810, answer the questions given below. The marks obtained in English, Physics and Social Science exceed the marks obtained in Mathematics and Chemistry by. निम्नलिखित वृत्तारेख, एक छात्र द्वारा एक परीक्षा में विभिन्न विषयो में प्राप्त अंक दर्शाता है, यथा भौतिकी (Ph), रसायन (Ch), गणित (M), सामाजिक विज्ञान (SS) और अग्रेंजी (E)। मान ले कि परीक्षा के लिए प्राप्त कुल अंक 810 है : अंग्रेजी, भौतिकी और सामाजिक विज्ञान में प्राप्त अंक गणित तथा रसायन में प्राप्त अंको से कितने अधिक है?

There are 200 questions in a 3 h examination. Among 200 questions, 50 are from Mathematics, 100 are from GK and 50 are from Science. Ram spent twice as much time on each Mathematics question as for each other question. How many minutes did he spend on Mathematics questions ?

Acidity or alkalinity of a solution depend upon the concentration of hydrogen ion relative to that of hydroxyl ions. The product of hydrogen ion & hydroxyl ion concentration is given by K_(w) = [H^(+)][OH^(-)] the value of which depends only on the temperature & not on the individual ionic concentration. If the concentratoin of hydrogen ions exceeds that of the hydroxyl ions, the solution is said to be acidic, whereas, if concentrations of hydroxyl ion exceeds that of the hydrogen ions, the solution is said to be alkaline. The pH corresponding to the acidic and alkaline solutions at 25^(@)C will be less than and greter than seven, respectively. To confirm the above facts 0.5 M CH_(3)COOH is taken fro the experiments. [Given : K_(a) of acetic acid = 1.8 xx 10^(-5) ] If pH of solution is double what will be the concentration of acetic acid-
