Answer: B) 1 Explanation: The pattern follows the palindrome sequence. Here the digits 0 1 4 7 8 5 8 3 6 9    9 6 3 8 5 8 7 4 1 0   0 1 4 7 ... So the next digit in the sequence is 1.

Answer: D) 38 Explanation: Let no. of boys be 'B' and no. of girls be 'G' Here from given data, B + G = 1650 .....(1) B - G = 400 .....(2) From (1) & (2), we get 2B = 2050 => B = 1025 => G = 1650 - 1025 = 625 Hence, the % of girls = 625 x 100/1650 => 38% (approx).

Answer: B) 540 Explanation: Here the LCM of 54, 60 is   => 2 x 3 x 3 x 3 x 10 = 6 x 9 x 10 = 54 x 10 = 540.

Answer: B) 3 kmph Explanation: Let the speed of the stream = x kmph   From the given data,    129+x+129-x=3 hrs 3x2 = 27   => x = 3 kmph   Therefore, the speed of the stream = 3 kmph

Answer: D) All the above Explanation: Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation.   Mutations are changes in the DNA. A single mutation can have a large effect. 1) mutation - an alteration in DNA sequence, various types 2) intragenic recombination - results in entirely new associations of genes not present in either parental genome. Two forms of intragenic recombination: a) crossing overb) independent assortment3) reticulation – acquisition of genetic material from unrelated or relatively unrelated sources (e.g., hybrid species, horizontal gene transfer).

Answer: B) 10000 Explanation: Let his monthly salary be 'P' 20% on children's education = 20P100 = P5 50% on food and transport = 50P100 = P2 1000 on rent => P - P5 - P2 - 1000 = 2000=> 3P = 30000=> P = 10000   Therefore, his monthly salary = Rs. 10,000
