Answer : 1. "29"
Explanation :
Answer: A) 29 Explanation: Let the five consecutive odd numbers be x-4, x-2, x, x+2, x+4 According to the question, Difference between square of the average of first two odd number and the of the average last two odd numbers is 396 i.e, x+3 and x-3 ⇒x + 32 - x - 32 = 396⇒ x2 + 9 + 6x - x2 + 6x - 9 = 396⇒ 12x = 396⇒ x = 33 Hence, the smallest odd number is 33 - 4 = 29.

Q: In a note collection, there is one new Rs.2000 note for every three old Rs.500 notes. 10 more new Rs.2000 notes are added to the collection and the ratio of new Rs.2000 notes to old Rs.500 notes would be 1: 2. Based on the information, the total number of notes in the collection now becomes? 2016 05b5cc777e4d2b41977750084

Answer : 4. "90"
Explanation :
Answer: D) 90 Explanation: Let 'x' be the number of new Rs.2000 notes. Given for one new 2000 note there are three old 500 notes. i.e, 3x Given 10 more new Rs.2000 notes are added to the collectionand the ratio of new Rs.2000 notes to old Rs.500 notes x+103x=12⇒x=20 Therefore, number of new Rs.2000 notes = x+10 = 30. old Rs.500 notes = 3x = 60. Thus, the total number of notes in the collection = 30 + 60 = 90.

Answer : 3. "in the nucleus, mitochondria, and chloroplasts."
Explanation :
Answer: C) in the nucleus, mitochondria, and chloroplasts. Explanation: All of the genetic information in a cell was initially thought to be confined to the DNA in the chromosomes of the cell nucleus. It is now known that small circular chromosomes, called extranuclear, or cytoplasmic, DNA, are located in two types of organelles found in the cytoplasm of the cell. These organelles are the mitochondria in animal and plant cells and the chloroplasts in plant cells. Chloroplast DNA (cpDNA) contains genes that are involved with aspects of photosynthesis and with components of the special protein-synthesizing apparatus that is active within the organelle. Mitochondrial DNA (mtDNA) contains some of the genes that participate in the conversion of the energy of chemical bonds into the energy currency of the cell—a chemical called adenosine triphosphate (ATP)—as well as genes for mitochondrial protein synthesis.
