Answers :
1) Answer: C
2) Answer: C
3) Answer: D
Sinθ + cosecθ = 2
Here, sinθ = 1, cosecθ = 1
Sin100θ + cosec100θ = 1
= 1 + 1 = 2
4) Answer: C
5) Answer: D
Cosecθ + cosec²θ = 1
Cosecθ = 1- cosec²θ
Cosecθ = – cot²θ
cot²θ = – cosecθ                               ..(i)
(cot12θ – 3cot10θ + 3cot8θ – cot6θ )
= (– cot²θ)³
= ((cosecθ)² – cot²θ)            (from eq (i))
= (cosec²θ – cot²θ)³ = 1³ = 1
6) Answer: C
Expenditure on a operations annually
=16 / 100 × 72 crores
= 11.52
7) Answer: B
Annually expenditure on miscellaneous
= 24 / 100 × 72 = 17.28
Monthly expenditure = 17.28 / 12
= 1.44
8) Answer: A
Expenditure on miscellaneous annually = 17.28
Expenditure on research of Nano tubes
=17.28 ×5 / 100 = 0.864
9) Answer: D
Total expenditure on interest and miscellaneous = 44%
Total expenditure on tax and salary = 40%
Required % = 4 / 40 × 100 = 10%
10) Answer: B
Total amount spent on Raw material = 50% of interest
= 10%
Ratio of amount of expenditure on Rent and Raw material = 1 : 2 → 10 %
Rent = 5%
Rent = 5 / 100 × 720000000
= 36000000
