During an experiment, two students were asked to prepare a 10% (Mass/mass) solution of salt in water. Rahul dissolved 10 g of salt in 100 g of water while Priya prepared it by dissolving 10 g of salt in water to make 100 g of solution. (a) Do the two solutions have same concentration ? (b) Calculate mass/mass percentage in each case. (c ) Whose measurements are correct for the experiment ?

The following 'precautions' were listed by a student in the experiment on study of 'Dependence of current on potential difference'. (A) Use copper wires as thin as possible for making connections. (B) All the connections should be kept tight. (C) The positive and negative terminals of the voltmeter and the ammeter should be correctly connected. (D) The 'zero error' in the ammeter and the voltmeter should be noted and taken into consideration while recording the measurements. (E) The 'key' in the circuit, once plugged in, should not be taken out till all the observations have been completed. The 'precautions' that need to be corrected and revised are :

Two schools P and Q want to award their selected students on the values of Tolerance, Kindness and Leadership. The school P wants to award Rs. x each, Rs. y each and Rs. z each for the three respective values to 3, 2 and 1 students respectively with a total award money of Rs. 2,200. School Q wants to spend Rs. 3,100 to award its 4, 1 and 3 students on the respective values (by giving the same award money to the three values as school P). If the total amount of award for one prize on each value is Rs. 1,200, using matrices, find the award money for each value. Apart from these three values, suggest one more value which should be considered for award.
