Answers:

1). Answer: d.

(16)²x (28)²/ (64)² = 49

2). Answer: A

Let principal = Rs. x

∴ Amount a. = 5x

S.I. = A – P

S.I. = 5x – x = Rs.4x

4x =x*16*r/100

Rate% = 25%

3). Answer: c

Ratio of second number: third number= 7:9=21:27

Ratio of first number: third number    = 8:27

Ratio of three numbers= 8:21:27

8x+21x+27x=168

X=3

Second number=21×3=63

4). Answer: c

One day work of A=1/40

One day work of B=1/25

In 8 days A completed 8*1/40= 1/5 work

Remaining 4/5 of the work was completed b y B

4/5*25=20 days

5). Answer: d

6). Answer: d.

x = 50 × 6 × 8 /40 × 20 = 3 hours

7). Answer: a.

21C2=21×20/2=210

8). Answer: a.

Perpendicular height of the largest triangle drawn in a semi-circle of radius r = r

∴ Area of the largest possible triangle = 1/ 2 (base × height) = 1/ 2 (2r) × (r) = r²

9). Answer: b.

Let the number be x

Then, x × 4/ 5 × 3/ 4 × 25 /100 = 66

⇒ x = 66 × 20 /3 = 440

∴ 25 per cent of the number = 440 × 25/ 100 =110

10). Answer: d.

Let the number of women be x

400 × 5 /(x × 4) = 10 /9

400 × 5 × 9 = 10 × x × 4

∴ x = 400 × 5 × 9/ (10× 4 )= 450
