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

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

Area of the rhombus =$\\frac{1}{2}*12*14 = 84$<\/p>\n

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

Let the breadth of the rectangle be x.
\nLength = 1.5x
\n2(x+1.5x) = 23+11+16 = 50
\n2.5x = 25
\nx = 10
\nLength = 1.5*10 = 15<\/p>\n

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

Volume of cylindrical tank = $\\pi r^2 h$ = $\\frac{22}{7}* 7\/2 * 7\/2 * 10$ =385 $m^3$.
\nHence, time taken =385\/2 minutes = 192.5 minutes = 3 hours 12.5 mins<\/p>\n

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

Let the base and height be b and h respectively. Hence, the original area is = 1\/2*b*h. After changing the base and height, area= 1\/2 * (0.9b) * (1.1h) = 0.99 (1\/2*b*h) = 198 sq-cm
\nHence, (1\/2*b*h) = 198\/0.99 = 200 sq-cm<\/p>\n

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

Total surface area of solid hemisphere =$3\\pi r^2 = 3\\frac{22}{7}*7*7$ = 462<\/p>\n

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

Since Angle XEA and XFC are corresponding angles,
\nAngle XEA = Angle XFC = 100 degrees
\nAngle XFC + Angle XFD = 180 degrees
\nAngle XFD = 180-100 = 80 degrees<\/p>\n

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

Since the sum of exterior angles on the same side of the transversal is equal to 180 degrees,<\/p>\n

Angle XEB + Angle DFY = 180 degrees<\/p>\n

110 + Angle DFY = 180<\/p>\n

Angle DFY = 180-110 = 70 degrees<\/p>\n

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

Consider the hexagon ABCDEF as shown.Join BF, CF and CE.<\/p>\n

 <\/p>\n

<\/p>\n

The hexagon is divided into 4 triangles.<\/p>\n

Sum of angles of hexagon = 180*4 = 720 degrees.<\/p>\n

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

Since the sum of the exterior angles of the triangles is 360 degrees,
\nExterior Angle to A = 360-(120+150) = 90 degrees.<\/p>\n

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

Area of circle = $\\pi r^2$ and circumference is $2 \\pi r$.
\nThus, the ratio is $\\frac{r}{2}$
\nNow, the side of the square will be equal to the diameter of the circle.<\/p>\n

=> Diameter = 2r = 8.
\n=> r\/2 = 2<\/p>\n

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

4.5 x l = 5 x 5
\nSo, l = 25\/4.5 = 5.56 metres.<\/p>\n

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

The diagonal of a square is $ \\sqrt {2}$ times the side. Let us assume that ‘a’ is length of side of the square.<\/p>\n

$\\sqrt{2}a$ = 52<\/p>\n

$\\Rightarrow$ a = $26\\sqrt{2}$<\/p>\n

So, area = $ a ^{2}$ = $(26\\sqrt{2})^{2}$ = 1352 (Answer :C)<\/p>\n

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

The perimeter of the square = 20. So, the side is 20\/4 = 5 metres. The circumference of the circle is 2 x $ \\pi$ x r = 2 x 3.14 x 2.5 = 15.70<\/p>\n

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

circumference of circle = 2\u03c0R = 35.2<\/p>\n

R is the radius if circle<\/p>\n

R= 5.6 cm<\/p>\n

Area of circle = \u03c0$(R)^2$ = 3.14 \u00d7 $(5.6)^2$ = 98.56 sq cm<\/p>\n

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

The area of rectangle = l x b = l x $ \\frac {l}{3} = \\frac{l^{2}}{3}$
\nThe area of square = $ l ^ {2}$
\nSo, the req. ratio = $ l ^ {2}$ : $\\frac{l^{2}}{3}$ = 3:1<\/p>\n\n
