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

Let the two digits be x & y From given data in the question, we get x + y = 3(x - y) x + y = 3x - 3y => 2x = 4y x/y = 2/1 For having the 2:1, numbers satisfying are 12, 21, 24, 42, 36, 63, 48, 84 From this 36 is eleminated because it is a perfect square and no others are prime or perfect squares. Hence, there exists 7 such 2-digit numbers => 12, 21, 24, 42, 63, 48, 84.

Answer: B) 137 Explanation: This can be done as,   (11 × 92)  -  (5 × 89)  -  (5 × 86)    = 1012- 445 - 430 = 137

Answer: C) 3.75 km Explanation: Let 'd' be the distance between A and BK -time = d/10 + d/9 = 19d/90 hoursL -time = 2d/12 = d/6 hoursWe know that, 10 min = 1/6 hoursThus, time difference between K and L is given as 10 minutes. => 19d/90 - d/6 = 1/6=> (19d-15d)/90 = 1/6=> 4d/90 = 1/6Thus,d= 15/4 km = 3.75 km. hence the distance between A and B is 3.75 km.

Answer: B) February Explanation: We know that the day repeats after every seven days.  Given that first day of the month is Tuesday i.e    1st - Tuesday 1+7 = 8 - Tuesday 8+7 =15- Tuesday 15+7=22-Tuesday 22+7=29-Tuesday But given that last day of the same month is Monday It is possible only in he month of Febuary with 28 days.

Answer: A) Uracil Explanation: A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.   In DNA, four bases have been found. They are 1. Adenine (A), 2. Guanine (G), 3. Cytosine (C) and 4. Thymine (T).   The first three of these bases are found in RNA also but the fourth which is Uracil (U) is absent in it. RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine.

The air around us is a mixture of gases, mainly nitrogen and oxygen, but containing much smaller amounts of water and other gases. Earth's atmosphere is composed of many gases. Their percentages by volume is given by::  78% Nitrogen, 21% Oxygen, 0.9% Argon, and 0.03% Carbon dioxide  And very small percentages of other elements.
