Priyanka and arti decided to doneate Rs 1600 for the army windows let priyanka 's shares as 'x' and arti share as'y'
(a) form a lienar equation in two variables
(b) if priyanka donates thrice the amount donated by arti then find out the amount donated by both

Sam went for an outing with his friends.They went to dominos to enjoy the delicious pizza. He was enjoying the pizza with his friends and share with them by slicing it. During slicing the pizza. he noticed that the pair of linear equations formed. (i.e.,straight lines) Let these pair of linear equations be y - 2x = 1 and 5y-x=14. If a pair of linear equations in two variables is inconsistent, then the lines represented by two ·equations are:

Arti, Bharti and Seema are partners sharing profits in the proportion of 3:2:1 and their Balance Sheet as on March 31, 2016 stood as follows : Bharti died on June 12, 2016 and according to the deed of the said partnership, her executors are entitled to be paid as under : (a) The capital to her credit at the time of her death and interest thereon @ 10% per annum. (b) Her proportionate share of reserve fund. (c) Her share of profits for the intervening period will be based on the sales during that period, which were calculated as Rs.1,00,000. The rate of profit during past three years had been 10% on sales. (d) Goodwill according to her share of profit to be calculated by taking twice the amount of the average profit of the last three years less 20% . The profits of the previous years were : 2013 – Rs.8,200 2014 – Rs.9,000 2015 – Rs.9,800 The investments were sold for Rs.16,200 and her executors were paid out. Pass the necessary journal entries and write the account of the executors of Bharti.

In 1931, Pauling defined the electronegativity of an atom as the tendency of the atom to attract electrons to itself when combined in a compound. The implication is that when a covalent bond is formed, the electrons used for bonding need not be shared equally by both atoms. If the bonding electrons spend more time around one atom, that atom will have a del- charge, and consequently the other atom will have a del+ charge. In the extreme case, where the bonding electrons are round one atom all of the time, the bond is ionic. Pauling and others have attempted to relate the electronegativity difference between two atoms to the amount of ionic character in the bond between them. Mulliken In 1934, Mulliken suggested an alternative approach to electronegativity based on the ionization energy and electron affinity of an atom. Consider two atoms A and B. If an electron is transferred from A to B, forming ions A^(+) and B^(-) , then the energy change is the ionization energy of atom A(I_(A)) minus the electron affinity of atom B(E_(B)) , that is I_(A)-E_(B) . Alternatively, if the electron was transferred the other way to give B^(+) and A^(-) ions, then the energy changed would be I_(B) - I_(A) . If A^(+) and B^(-) are actually formed, then this process require less energy , and (I_(A) - E_(B)) lt (I_(B) - E_(A)) Rerranging (I_(A)+E_(A)) lt (I_(A)-E_(B)) Now with respect to electronegativity for the same change, E.N_(A) lt E.N_(B) . Thus Mulliken suggested that electronegativity is proportional to I.E + E.A and could be regarded as the average of the ionization energy and the electron affinity of an atom. Electronegativity =((I+E))/(2) Mulliken used I and E values measured in electron volts, and the values were about 2.8 times alrger than the Pauling values. It is to be noted that I.E . and E.A values are defined for singular gaseous atoms. We have X atoms of A. if all the atoms gain one electron each the energy released is aeV . If Y atoms of A lose one electron each, then the energy absorbed is beV. Then the electronegativity of A on the Mulliken scale will be:

On her birth day, Seema decided to donate some money to children of an orphanage home. If there were 8 children less, everyone would have got Rs.10 more. However, if there were 16 children more, everyone would have got Rs. 10 less. Let the number of children be x and the amount distributed by Seema for one child be y (in Rs.). Based on the information given above, answer the following questions: How much amount Seema spends in distributing the money to all the students of the Orphanage?

Rajesh want to chose a best plan for his mobile phone. He has 2 options available with him. The first plan of company A, cost Rs 20 per month, with costing an additional 25 paise per minute. The second plan of company B charge Rs 40 per month, but calls cost 8 paise per minute. These two situations are shown below in the form of linar equations. The total cost of the two company's are given as : y =0.25 x + 20 and y = 0.8x + 40 Where, x is the minutes used any y is the total cost per month. If Rajesh decides to take first plan and calls for 90 minutes in a month, then how much amount he will have to pay ?
