To find the area of right angled triangle, we need to know the base and height or the length of any side if its aÂ 30-60-90 triangle

From statement I and III, two angles are 90Â° and 60Â°, => Third angle = 30Â°

In a 30-60-90 triangle, the hypotenuse is always twice as long as the side opposite the 30Â° angle and the side opposite the 60Â° angle isÂ âˆš3 times as long as the side opposite the 30Â° angle.

The ratio of sides opposite 30Â°, 60Â° and 90Â° angles =1Â : $\sqrt{3}$ : 2

LengthÂ of the side opposite the 90Â° angle (hypotenuse) = 5 cm

=> Length of side opposite the 30Â° angle = $\frac{5}{2}=2.5$ cm

and length of side opposite to 60Â° angle = $2.5 \sqrt{3}$ cm

$\therefore$ Area of triangle = $\frac{1}{2} \times 2.5 \times 2.5 \sqrt{3} = 3.125\sqrt{3}$ $cm^2$

Thus, statement II is redundant.

=> Ans – (B)

All the three friends will meet at the starting point again after X seconds, such that X is the LCM of the times taken by J, K and L to complete one round.

=> LCM of 12, 18 and 20 = 180 seconds = 3 minutes.

Hence 3 minutes is the answer.

Let the speed of boat in still water be v and the speed of water be x.

Boat speed while going upstream = v-x = 28

Boat speed while going downstream = v+x = 32

=> 2v = 60 => v = 30

Hence, none of these is the correct answer.

Part of tank emptied in 1 hour by the
leak

$\frac{1}{2}$ – $\frac{2}{7}$ = $\frac{1}{14}$

The leak will empty the tank in 14 hours.

Total members = 240

Total males = 160

Total Females = 80

Absolute Difference between number of females who are non-graduates and number of males who are graduates = 24 – 20 = 4

Total members = 240

Total males = 160

Total Females = 80

=>Â sum of the number of females who are graduates and the number of males who are non-graduates = 136 + 60 = 196

Total members = 240

Total males = 160

Total Females = 80

Ratio of total number of males to number of female non-graduates = 160 : 20 = 8 : 1

Parineetaâ€™s present age = 33 – 9 = 24 yrs.
Manishaâ€™s present age = 24 – 9 = 15yrs
Difference between Manisha and Deepali’s prresent ages = Parineeta’s present age
Deepaliâ€™s present age = Parineeta’s present age + Manisha’s present age = 24 + 15 = 39 yrs.
Ratio of the present age of Manisha and Deepali = 15 : 39 = 5 : 13
x = 13

Total marks = 24 x 56 = 1344
Sum of actual marks = 1344 – (44 + 45 + 61) + (48 + 59 + 67) = 1368
Actual Average = $\frac{1368}{24}$ = 57

$2a^{2}+a-1=0$
We get the factor as:
a=-1, a=0.5

$12b^{2}-17b+6=0$
Solving, we get the factor as,
b= 1.5, b= .75

Hence, b>a
Option A is correct option.

Soving the quadratic equations we get,
$a^{2}-5a+6=0$
i.e (a-2)(a-3)=0
i.e a=2, a=3

$2b^{2}-13b+21=0$
i.e (b-3.5)(b-3)=0
i.e b= 3.5 and b=3

Hence, we can deduce that $a\leq b$
Therefore, option B is correct.

$a^{2}+5a+6=0$
i.e (a+2)(a+3)=0
i.e a=-2, a=-3

.$b^{2}+7b+12=0$
i.e (b+4)(b+3)=0
i.e b=-4, b=-3

Hence, we can deduce that $a \geq b$.
Therefore, option E is correct.

Total amount = 20 x 7 + 8 x 22 + 6 x 175 + 7 x 43
= 140 + 176 + 900 + 301
= Rs1,667

Marked price = 78,350 + 30% of 78,350 = Rs 1,01,855
Price after discount = 101855 -20% of 101855 = Rs 81,484
Profit = Rs 3,134

The profits are divided in the ratio of [Investment X time period]
So, this number for A is 30k X 12 = 360k
For B it is 24k X 4 + 18k X 12 = 240k
For C it is 42k X 4 + 32k X 8 = 424k

So, B’s share in the profit will be $\frac{240}{360+240+424} \times 11960 = 2803.125 \approx 2803$

Loss percent
= [$\frac{loss}{10}$]2 %
= [$\frac{12}{10}$]2Â %
= $\frac{36}{25}$ %
= 1$\frac{11}{25}$ %

Probability that at least 1 is blue => 1 – (probability that none is blue) => 1 – $(\frac{^{11}C_4}{^{15}C_4})$ = $\frac{69}{91}$

Number of ways of selecting 2 red balls in 2 chances = $^{6}C_2$
Probability of 2 red balls in 2 chances = $\frac{^{6}C_2}{^{15}C_2}$ = $\frac{1}{7}$
Number of ways of selecting 2 blue urns and 1 yellow urn = $^{4}C_2* ^{3}C_1$ = 18
Probability of selecting 2 blue urns and 1 yellow urn Â = $\frac{18}{^{15}C_3}$ = $\frac{18}{455}$
