Answer : 4. "All the above"
Explanation :
Answer: D) All the above Explanation: Intermolecular forces : The forces of attraction present in between the molecules or atoms or compounds is termed as intermolecular forces. The molecule HCl is composed of hydrogen and chlorine atom. There is high difference in electronegativities therefore, it is polar in nature. The H end of HCl is permanently slightly positive charge. The Cl end of HCl has a permanent slight negative charge. the "H" in one molecule is attracted to the "Cl" in a neighbor. The intermolecular force is weak compared to a covalent bond. But this dipole-dipole interaction is one of the stronger intermolecular attractions. It also has hydrogen bonding and dispersion forces. Dispersion forces are the weakest forces which are present in between all molecules or atoms.Hydrogen bonds are present in molecules having at least one H-A bond where A is the strong electronegative atom (mainly F, Cl and N).

Answer : 1. "32"
Explanation :
Answer: A) 32 Explanation: Given ratio of number of sheep and horses = 4 : 15Let number of sheep and horses are 4k and 15k Number of horses = 13200/110 = 120 Now 15K = 120 and k = 8 Number of sheep = 4k = (4 x 8) = 32

Answer : 2. "decrease 12%"
Explanation :
Answer: B) decrease 12% Explanation: Given the price of a commodity is decreased by p = 20% And its consumption is increased by q = 10% Now, required increase or decrease in the expenditure on the commodity can be p + q + pq/100 = -20 + 10 - 200/100 = -10 - 2 = -12%. Hence, decrease in the expenditure = 12%
