Answers :
1) Answer: B
2) Answer: D
x = 15
y = 10
tan (6x-3y) = tan(60) = √3
3) Answer: B
3cotθ = 4 cosθ
¾ = sinθ
Cos2θ = 1 – 2sin²θ
= 1 – 2 × 9/16
= -1/8
4) Answer: B
5) Answer: B
Cosec²θ + cot²θ = 7
Cosec²θ – cot²θ + 2cot²θ = 7
1 + 2cot²θ = 7
Cot²θ = 3
θ = 30°
6) Answer: D
Rent expenditure = 16%
Hence ⇒ 16/100 × 50000
= 8000/-
7) Answer: A
∵ 1% → 3.6°
26% → 3.6 × 26
= 93.6°
8) Answer: B
Expenditure on food = 23%
Savings = 20%
% of expenditure on food
= (23-20) / 20 × 100
= 3/20 × 100
= 15%
9) Answer: C
If expenditure on clothes
15% ⇒ 3000
Then, expenditure on education
26% = 3000/15 × 26
= 5200
10) Answer: A
F/C = 4/3 = 20/15
Difference ⇒ 5%
Angle for 5% = 5/100 × 360
= 18
