b) 150
c) 300
d) 250
Answers :
1) Answer: a)
Sin θ – cos θ = √2cos θ
Squaring both side,
(sin θ – cos θ)2 = 2cos2 θ
sin2 θ +cos2 θ – 2 sin θ cos θ = 2 cos2θ
sin2 θ = cos2 θ + 2 sin θ.cos θ
Add Sin2 θ on both sides
2 sin2 θ = sin2 θ +cos2 + 2sin θ cos θ
2 sin2 θ = (sin θ + cos θ) 2
sin θ + cos θ = √2 sin θ
2) Answer: b)
The Number which have 1 or 6 in unit’s digits are 1, 11, 21, 31, 41, 51, 61, 71, 6, 16, 26, 36, 46, 56, 66.
Total number with unit’s digit as 1 or 6 = 15
Total number = 75
Required percentage = (15*100)/ 75 = 20%
3) Answer: c)
Man : His son
3 : 1
Man : His wife
2 : 1
Man : Wife : Son
6 : 3 : 2
Average age of this family = 22
Total age of this family = 22*3 = 66
6x + 3x+ 2x = 66 => 11x = 66
X = 6
Sum of ages of wife and son = 3x + 2x = 5x = 5 * 6 = 30 years
4) Answer: c)
No. of diagonals of polygon = n (n – 3)/2 = 8 (8 – 3) / 2 = (8 * 5) /2 = 20
5) Answer: c)
The angle made by any side with the in centre = 90° + half the opposite angle.
= 90° + ∠P/2
= 900 + ½ *600 = 90° + 30° = 1200
6) Answer: c)
P = 1/8 hours
R = 1/6 Hours
P + R = 1/8 + 1/6 = 7/24
= 3 (3/7) hours
7) Answer: b)
Area of Trapezium = Half of sum of two parallel Sides * Heights
= (½)* [(s1+s2) * H]
= (28 + 12) /2 * 15 = 300 cm2
8) Answer: c)
The ordinate of the point is m2 + 5m – 12
Abscissa = 6m
6m = m2 + 5m – 12
m2 + 5m – 6m – 12 = 0
m2 – m – 12 = 0
m2 – 4m + 3m – 12 = 0
m (m – 4) + 3 (m – 4) = 0
m = – 3
m = 4
9) Answer: b)
Curved surface area of the cylinder= 2πrh = 660 m2
Volume of the cylinder = πr2h = 2310 m3
(πr2 h)/(2πrh )= (2310 )/(660 )
R = 7
Curved surface area of the cylinder= 2πrh = 660 m2
= 2* 22/7 * 7 * h = 660 m2
= > h = 15 m
10) Answer: a)
Total Fruits = x
According to the question, unsold fruits were remain same
(x – 15x/100 – 60) = (x – 10x/100 – 65)
15x/100 + 60 = 10x/100 + 65
15% of x – 10 % of x = 65 – 60
5x/100 = 5
5x = 500
X = 100
Total number of fruits = 100
