उत्तर : 2. "Monosaccharides can be classified according to the spatial arrangement of their atoms."
व्याख्या :

Answer: B) Monosaccharides can be classified according to the spatial arrangement of their atoms. Explanation: Monosaccharides, also called simple sugars, are the most basic units of carbohydrates. They are fundamental units of carbohydrates and cannot be further hydrolyzed to simpler compounds.   Hence, Monosaccharides can be classified according to the spatial arrangement of their atoms is true about Monosaccharides.

उत्तर : 1. "equal to both the coupon rate / current yeild"
व्याख्या :

Answer: A) equal to both the coupon rate / current yeild Explanation: Yield to maturity is a concept for fixed rate bonds and is the internal rate of return i.e. the rate at which future flows are discounted on a compound basis to give the present value of the bond including accrued interest.

उत्तर : 1. "210 kN/mm2"
व्याख्या :

Answer: A) 210 kN/mm2 Explanation: It is useful to have a property of a material that is independent of the size of the sample and can be use to compare its elastic properties with another - this is called the Modulus of Elasticity for the material. The modulus of elasticity is defined as:   Modulus of elasticity = Stress / Strain   There are three types of moduli. They are : (a) the Young Modulus - tensile and compression longitudinal stress (b) the shear modulus - a shearing stress (c) the bulk modulus - volume changes of the specimen.
