General Science Notes for RRB Exams (PDF)<\/a><\/p>\n\n

Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

5(4x-3\/2) + 2x = 4-3x\/2<\/p>\n

20x – 15\/2 + 2x = 4-3x\/2<\/p>\n

22x + 3x\/2 = 4 + 15\/2<\/p>\n

47x\/2 = 23\/2<\/p>\n

x = 23\/47<\/p>\n

So the answer is option A.<\/p>\n

2)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

$(a-b)^2 = (a+b)^2 – 4ab$<\/p>\n

$(a-b)^2 = (23)^2 – 4(132)$<\/p>\n

$(a-b)^2 = 529 – 528$<\/p>\n

$(a-b)^2 = 1$<\/p>\n

$a-b = +1 or -1$<\/p>\n

So the answer is option D.<\/p>\n

3)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

WKT, sum of 1st n natural numbers = $\\frac{n(n+1)}{2}$<\/p>\n

$7+8+9+10+……+50 = (1+2+3+…..+50)-(1+2+3+….+6)$<\/p>\n

This equals $\\frac{(50)(51)}{2} – \\frac{(6)(7)}{2} = 1275 – 21 = 1254$<\/p>\n

So the answer is option B.<\/p>\n

4)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

$a^3+b^3 = (a+b)^3-3ab(a+b) = 13^3-3(40)(13) = 2197 – 1560 = 637$<\/p>\n

So the answer is option B.<\/p>\n

5)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

$\\text{cot} \\theta = \\frac{5}{12}$<\/p>\n

$\\text{cosec}^2 \\theta$ = $1+\\text{cot}^2 \\theta = 1+{(\\frac{5}{12})}^2 = \\frac{169}{144}$<\/p>\n

$\\text{cosec}\\theta = \\frac{13}{12}$<\/p>\n

So the answer is option B.<\/p>\n

6)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

$48-3 = 45$
\nApplying tan on both sides
\n$tan (48-3)^\\circ = tan 45^\\circ$ \u2192 (1)
\nWe know that $tan (A-B)^\\circ = \\dfrac{tan A^\\circ – tan B^\\circ}{1+tan A^\\circ.tan B^\\circ}$
\nThen, (1) becomes
\n$\\dfrac{tan 48^\\circ – tan 3^\\circ}{1+tan 48^\\circ.tan 3^\\circ} = 1$ (Since, $tan 45^\\circ = 1$)<\/p>\n

$tan 48^\\circ – tan 3^\\circ = 1+tan 48^\\circ.tan 3^\\circ$
\n\u21d2 $tan 48^\\circ – tan 3^\\circ – tan 48^\\circ.tan 3^\\circ = 1$<\/p>\n

7)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

$4\\times x = 0.20\\times120$
\n\u21d2 $x = \\dfrac{0.20\\times120}{4} = 6<\/p>\n

8)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let the smallest number be x.
\nGiven, $\\dfrac{x+x+1+x+2+x+3+x+4+x+5+x+6}{7} = 4$
\n\u21d2 7x+21 = 28
\n\u21d2 7x = 7
\n\u21d2 x = 1
\nHence, The smallest number = 1.<\/p>\n

9)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let C be 2x.
\nThen B = 50% of 2x = x
\nA = 150% of 2x = 3x.
\nGiven, 3x+x+2x = 168
\n\u21d2 6x = 168 \u21d2 x = 28
\nTherefore, Smallest number = 28<\/p>\n

10)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Amount received by A,B,C and D be 5x,6x,4x and 3x respectively
\nB-D=6000 i.e 6x-3x=6000
\nx=2000
\nTotal sum is 5x+6x+4x+3x=18x=36000<\/p>\n

11)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Using BODMAS rule,
\n= 6 – 36 x (3\/6) + 5
\n= 6 – 18 + 5 = -7
\nHence, option C\u00a0is the correct answer.<\/p>\n

12)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

We know, Work done = Force x time<\/p>\n

According to the question,<\/p>\n

Work done = 120 x 2 Joules<\/p>\n

Work done = 240 Joules<\/p>\n

13)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

By simplification we get
\n=12+4.32-5.6
\n=10.72<\/p>\n

14)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

After\u00a0simplify all the fractions given in options, we can get the odd one.<\/p>\n

$\\frac{32}{88}$ =\u00a0$\\frac{4}{11}$<\/p>\n

$\\frac{84}{209}$ (This is not equal to $\\frac{4}{11}$.)<\/p>\n

$\\frac{64}{176}$ =\u00a0$\\frac{4}{11}$<\/p>\n

$\\frac{20}{55}$ =\u00a0$\\frac{4}{11}$<\/p>\n

15)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

By simplifying we get
\n(292.089+123.345)=415.434<\/p>\n\n
