Solution:

1. Answer: A

3207 – 976 – 1781=450

2. Answer: D

Numbers divisible by 7 between 4 and 100 are  7,14,21,28,35,42,49,56,63,70,77,84,91 and 98

3. Answer: A

The maximum capacity of a container which can measure the milk in each container an exact number of times, is the H.C.F. of 60 and 165.

H.C.F. of 60 and 165 = 15

4. Answer: B

2/5*105-3/4*48=6

5. Answer: A

The contribution by the workers in the workshop = 196 – 16 = Rs. 180

Let the number of workers in A grade be x and in B grade be y. ∴ x ² + y² = 180

Now, by putting x = 12 and y = 6, we get x ² + y² = 12² + 6² = 180 ∴ x + y = 12 + 6 = 18

6. Answer: D

The amount of alcohol in 15 litres of mixture = 15 × 20/100 = 3 litres

Volume of mixture on addition of 3 litres of water = 15 + 3 = 18 litres

Percentage of alcohol in new mixture = 3 × 100/18% = 16·67%

7. Answer: B

Let the distance = D and Time = T

∴ Original speed = D/T …(1)

As per question, New speed = (D /2) /(2 × T) = 1/4 * D/T

∴Reqd. Ratio = New speed: Original speed = 1/4* D/T : D/T = 1: 4

8. Answer: B

Let the principal sum be Rs. P. Then ∴ Difference between C.I. and S.I. for 2 years is

 

 

 

P = 1·50 × 100 = Rs. 150

9. Answer: B

Let the number be x.

X+x/2=360

3/2 x=360

x=240, x/2=120

10. Answer: C

Let the length of rectangle = l metre,

Then  Breadth = 3/4* l.

∴l× 3/4 *l = 192 m²⇒ l² = 4/3 × 192 = 256 = (16)²∴ l = 16 m

∴ Perimeter of rectangle = 2 (l + b) = 2 × (16 + 12) = 56 m
