Answer: C) 20 Explanation: From first figure : each fig has the value of 20 => It has inside 4 figures => Each individual figure has the value of '5' From second => Each Triangle has the value of '1' (bcoz it contains two in each) From third => Figure star has the value of '4' Then in fourth => 4 + 1 + 15 = 20

Answer: D) Nagpur Explanation: With India's pledge to go all electric by 2030, Nagpur will be the first city in the country to adopt electric cabs as the country moves a step closer to its goal. The pilot project will see around 200 e-cabs in Nagpur with the local body to provide for the charging stations across the city. Currently, Mahindra and Honda are few of the car-manufacturers who have electric and hybrid vehicles in their line-up. We do hope that the situation changes, as hybrid and electric vehicles will help in the growing pollution in India. Countries such as France, Netherland and Belgium have already started to adopt electric and hybrid vehicles.

In a chemical reaction, substances (elements or compounds) called reactants are changed into other substances (compounds or elements) called products. Hence, reactants are those which start the chemical reaction.   For example: 1. In the burning of natural gas, methane (CH4) and oxygen (O2) are the reactants in the chemical reaction. are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction.   2. H2+O2 ----> H2O Here H2 & O2 are called Reactants and H2O is called Product.

Answer: C) 32 years Explanation: Let Shilpa's present age is p years According to question, p = 4(x+4) – 4(x–4) p = 4x+16 – 4x+16 p = 32 Shilpa's present age = 32 years Rajeev is four years older than Shilpa => Shilpa's present age = Rajeev's age 4 years before. => Rajeev's age 4 years before = 32 years.

Answer: A) 1 TB Explanation: 1 TB  >  1 GB  >  1 MB  >  1 KB   1 Tb (Tera Byte) = 1024 GB 1 GB (Giga Byte) = 1024 MB 1 MB (Mega Byte) = 1024 KB 1 KB (Kilo Byte) = 1024 Bytes 1 Byte = 8 Bit   Hence, largest unit of information is TB (Tera Byte) and smallest unit of information is Bit.

Answer: D) 89 Explanation: This can be done in a method called Approximation. Now,  52 + 63 + 6 + 72 = ? x 3.3425 + 216 + 6 + 49 = ? x 3.34296 = ? x 3.34? = 2963.34 = 88.622 ≅ 89

Answer: B) 18 gms Explanation: The molar mass of H2O can be calculated as the following. M(H2O)= [2 x M(H)] + [M(O)]. And we know that M(H) = 1g/mol, M(O) = 16g/mol. So, M(H2O)= 2x1 + 16 = 18g/mol, That means 1 mole of H2O contains 18g.   Hence, one mole of H2O corresponds to 18 grams.
