व्याख्या :

Out of 4 fruits, any 3 are chosen by 4 families.So the combinations areApple - A Cherries - C Banana - B Grapes - G1) ACB2) ACG3) BCG4) GAB By 2nd condition, Miller family uses either i)ACB or ii)ACGNow we have Robin, Mandy and Miller who uses apples (ACB,ACG,GAB)while Miller and Mandy both uses A and C. That leaves GAB for Robin. By 3rd condition Flure uses either C or G. So if we leave out the terms containing both C and G, we are left with ACB and GAB Now, for the time being let's suppose Robin is not a Flure.So ACB is taken by Flure. So ACG has to be Miller and that leaves BCG to be Clark. So we get Robin - Jacob(GAB). By 4th and 2nd conditions Erica and Mandy belong to the first two. That leaves Stacy - Clark(BCG). By 2nd condition Mandy is not a Miller, so we get Mandy - Flure(ACB) and that leaves Erica - Miller(ACG).

उत्तर : 1. "Uracil"
व्याख्या :

Answer: A) Uracil Explanation: A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.   In DNA, four bases have been found. They are 1. Adenine (A), 2. Guanine (G), 3. Cytosine (C) and 4. Thymine (T).   The first three of these bases are found in RNA also but the fourth which is Uracil (U) is absent in it. RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine.

उत्तर : 2. "109.9446"
व्याख्या :

Answer: B) 109.9446 Explanation: The term gram formula mass is synonymous with molecular mass. So, to get this, we must add molar mass of all the elements in this compound.   Given compound is Lithium Sulphate - Li2SO4 Elemental calculation :: Li  -  Lithium   -   6.941    -     2   -   13.88200 %S  -  Sulfur     -    32.065   -    1   -   32.065 %O  -  Oxygen   -   15.9994  -    4   -   63.9976 % Now, total = 12.6264 + 29.1647 + 58.2090 = 109.9446    Hence, the gram formula mass of Li2SO4 = 109.9446.

उत्तर : 3. "P1V1 = P2V2"
व्याख्या :

Answer: C) P1V1 = P2V2 Explanation: Ideal Gas Law :: The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas: P1V1T1 = P2V2T2   Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.
