 Question Answer 1. B 2. B 3. B 4. D 5. A 6. B 7. D 8. C 9. A 10. B

Explanation:1.  H. C. F. Of 88, 132 and 220 = 44
No. of rows=88/44+132/44+220/44=10

Explanation:2. Suppose the smaller number is x, then the larger number = (x+ 1365). Therefore, x+1365 = 6x+ 15 5x = 1350 x = 270.
Thus, the smaller number = 270.

Explanation:3. OR Explanation:4.
Let the executive be X, Then total salary of the entire staff = 6400× (10 + X)
64,000 + 6400X = 13,600 × 10 + 4000× X
2400X = 72000
X = 30

Explanation:5. If you double the sides of a cube, the ratio of the surface areas of the old and new cubes will be 1: 4. The ratio of the volumes of the old and new cubes will be 1: 8. Weight is proportional to volume. So, If the first weighs 8 kilogram, the second weighs 8×8 kilogram = 64.

Explanation:6. Probability of getting less than 2 is p = 1/6
Probability of getting less than 2 in at least one throw is = pq + qp + pp Explanation:7.

Perimeter = Distance covered in 15 min. = 12000 x 15/60 = 3000 m.
Let length =  7/2 x metres and breadth = 5/2  x metres.
Then, 2(7/2 x += 5/2  x) = 3000 or x = 250.
Length = 875 m and Breadth = 625 m.
Area = (875 x 675) m2 = 590625 m2.

Explanation : 8. Let x be the side of the square.
Area of the rectangle = (x + 2) (x – 2) = 45
X2 – 4 = 45
X2 = 49
x = 7cm
Perimeter of the original square
= 4  × 7 = 28 cm

Explanation: 9. Cheese and powder milk at present have a combined production of 7430 + 14446 = 21876. A 20% increase will mean Explanation:10. [Source:- Jagranjosh]
