  4. 4.5

Answers:

1.Answer: C

1M = 2W = 3C

1M = 3C

1W = 3/2C

1M+1W+1C = 3C + 3/2C+1C = 11/2 C

3C è 2 Days

11/2 è ?

(3×2×2) / 11 = 12/11 days

2.Answer: B

Downstream speed= 16/2 = 8kmph

Upstream speed=  16/4= 4kmph

Speed of the stream = (x-y)/2 = (8 – 4)/2 = 4/2 = 2 kmph

3.Answer: C

∴ q/p = r/ q

⇒ q2 = pr

⇒ q = √pr

4.Answer: C

5.Answer: A

tan 5°.tan 44°. tan (90° – 44°). tan (90° – 5°)

= tan 5° ⨯tan 44°⨯ cot 44°⨯ cot 5°

= tan 5°⨯cot 5° ⨯ cot 44° ⨯ tan 44° = 1 [tanθ.cotθ = 1]

6.Answer: B

7.Answer: d

9x2 – 30x +25

=9x2 – 15x – 15x + 25

=3x (3x – 5) – 5(3x – 5)

= (3x – 5)2

8.Answer: C

Speed = 10 × 5/18 = 50/18

Time = Distance / speed

= (250 ×18)/50 = 90 sec

= 1.5mins

9.Answer: B

600+22.5 – x = 600+13

622.5 – x= 613

X = 622.5 – 613

X= 9.5

10.Answer: D

5/(3+x) = 2/3

15= 6+2x

2x= 9

X= 4.5
