Three friends went to a hotel and had breakfast to their taste, paying ₹16, ₹17 and ₹21 respectively : If they have spent 3 times the amount that they have already spent, what would their mean expenditure be ?

Three friends went to a hotel and had breakfast to their taste, paying ₹16, ₹17 and ₹21 respectively : Find their mean expenditure.

Three friends went to a hotel and had breakfast to their taste, paying ₹16, ₹17 and ₹21 respectively i) Find their mean expenditure. ii) If they have spent 3 times the amount that they have already spent, what would their mean expenditure be? iii) If the hotel manager offers 50% discount, what would their mean expenditure be? iv) Do you notice any relationship between the change in expenditure and the change n mean expenditure?

Numerous forms of the periodic table have been devised from time to time. A modern version which is most convenient and widely used is the long or extended from of periodic table. The aufbau principle and the electronic configuration of atoms provide a theoretical foundation for the periodic classification. The horizontal rows are called periods. There are altogether seven periods. The first period consists of 2 elements. The subsequent periods consists of 8, 8,18, 18 and 32 elements respectively. The seventh period is incomplete and like the sixth period would have maximum of 32 elements. Elements having similar outer electronic configurations in their atoms are grouped in vertical columns. These are referred to as groups or families. According to the recommendations of IUPAC, the groups are numbered 1 to 18 replacing the older notation of groups 0, IA, IIA, ....VIIA, VIII, IB.....VIIB. Each successive period in the periodic table is associated with the filling up next higher principal energy level following aufbau sequence. The number of elements in each period is twice the number of atomic orbitals available in the energy level that is being filled. All the elements are classified into four blocks, i.e., s-block, p-block, d-block, and f-block depending on the type of atomic orbitals that are being filled with electrons. An element belongs to group 17 with atomic number is 17. What is the atomic number of the element belonging to same group and present in fifth period?

I borrowed ₹12000 from Prasad at 6% per annum simple interest for 2 years. Had I borrowed this sum at 6% per NA annum compounded annually, what extra amount would I have to pay?
