उत्तर : 1. "Rs. 5000"
व्याख्या :

Answer: A) Rs. 5000 Explanation: Let the amount invested by saketh = RS. p Now, that of sandeep = 20,000 x 6 saketh = 12 x p Ratio of their earnings = 120000 : 12p = 6000 : (9000 - 6000) => 12000012p = 60003000 => p= Rs. 5000 Hence, the amount investe by saketh  = Rs. p  = Rs. 5000.

उत्तर : 2. "480 kms"
व्याख्या :

Answer: B) 480 kms Explanation: Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kms Let the Charminar Express takes 't' hrs to catch Chennai express => 80 x t = 60 x (2 + t) => 80 t = 120 + 60t => t = 6 hrs   Therefore, the distance away from Hyderabad the two trains meet = 80 x 6 = 480 kms.

उत्तर : 1. "Weight"
व्याख्या :

Answer: A) Weight Explanation: An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

उत्तर : 1. "it contains two different elements joined by chemical bond"
व्याख्या :

Answer: A) it contains two different elements joined by chemical bond Explanation: We know that All compounds are molecules, but not all molecules are compounds. Water is a molecule because it is made from atoms that have been chemically combined. It is also a compound because the atoms that make water are not all the same - some are oxygen and some are hydrogen.   Hence, Water is a molecule and a compound.
