There are 3 types of expenditure in a car . 1st raw material ,2nd labour expenditure , 3rd is extra expenditure .The ratio of these expenditure are 4:3:2 .If 1st expenditure is increased by 10% ,2nd is increased by 8% and 3rd is decreased by 5% Find the percentage change in price of car .

In the crystalline solids the smallest repeating part in the lattice is known as unit cell. The unit cells are described as simple (points at all corners), body centred (points at all the corners and it the centre), face centred (points at all the corners and centre of all faces), and end centred (points at all hte corners and centres of two opposite and faces) unit cells. In two common tyupes of packing ccp and hcp, 26% of space is left unoccupied in the form of interstitial sites. For the stable ionic crystalline structures, there is difinite radius ratio limit for a cation to fit perfectly in the lattice of anions, called radius ratio rule. This also defines the coordination number of an ion, which is the number of nearest neighbours of opposite charges. This depeds upon the ratio of radii of two types of ions, r_(+)//r_(-) . This ratio for coordination numbers 3,4,6,and 8 is respectively 0.155 - 0.225, 0.225 - 0.414, 0.414 - 0.732 and 0.732 - 1 respectively. The number of atoms per unit cell in simple (s), body centred(b) , face centred (f) and end centred (e) unit cell decreases as

Which of the following statements are correct - 1. CCP structure has three different type of layers. 2. In CCP structure, first and fourth layers are repeated. 3. In an HCP structure, first and fourth layers are repeated. 4. In FCC packing, the neighboring face centered atoms touch each other.
