d) 667
Answers :
1). Answer: b)
Radius of circle= √ (42+32) = 5 cm
Area of circle = 22/7×5×5 = 78.6 cm2
2). Answer: b)
Central angle of Arc = 135o
Central Angle of a circle = 360o
Circumference of circle = 2×22/7×42 = 264 cm
Arc length = 135/360 (Circumference of circle)
= 3/8 (Circumference of circle)
= 3/8(264) = 99 cm
3). Answer: c)
A can do the whole work in 24×3/2= 36 days
B can do the whole work in 36/2=18 days
B will do half of the job in 18/2 =9 days
4). Answer: c)
Quotient = x/3
Remainder = x/2
By remainder theorem,
Dividend= Quotient x divisor + remainder
Y = x2/3+x/2
Y = x(x/3+1/2)
6y = x(2x+3)
5). Answer: b)
20% = 180
100% = 900
Marked Price = 900
Selling Price = 900 – 180 = 620
Ratio= 31: 45
6). Answer: a)
cosec4θ = 17 + cot4θ
Cosec4θ – cot4θ = 17
(Cosec2θ – cot2θ)(Cosec2θ+ cot2θ) = 17
Cosec2θ + cosec2θ – 1 = 17
2/sin2θ = 18
sin2θ =1/9
sinθ =1/3
7). Answer: b)
Average of multiples of 7 below 300 = (7+287)/2 = 147
8). Answer: b)
Total salary of 16 people = 16×500 = 8000
Salary after adding new people= 8000 + 1000 + 1200 + 1400 – 800
=10800
Average salary of the new group= 10800/18= 600
9). Answer: c)
Divisibility rule of 5= Last digit should be 0 or 5
Divisibility rule of 8= Last three digits should be divisible by 3
So the Answer is (1, 0)
10). Answer: b)
362+ 42=? + 272
1296 + 16 – 729 = 583
