Answers :

1). Answer: C

3/7× 14/5×15/21× x = 12

6/7x =12

X = 12 × 7/6 = 14

2). Answer: d

Cost price of the book = x

Profit = 160 – x

Loss s= x- 140 

2x = 160 + 140 = 300/ 2 = 150

3). Answer: B

5x – 4x = 2000

X = 2000

Babu’s salary = 2000*4 = 8000

4). Answer: 

Total age of ram and sita = 40

Ram: Ravi = 5 : 4

There is no common data to conclude answer.

5). Answer: D

(50×20)/ 60 = 50 / 3 = 16 2/ 3

6). Answer: B

2/3 work in 6 days —————– whole work done by A in  9 days

B = 1/ 18 days

A + B = 1/ 9 + 1/ 18 = 3 / 18 = 1/ 6

A and B can complete the job in 6 days

7). Answer: C

√x +1/√x = 4

Take square both sides

(√x)² + (1/√x)² = (4)²

(X + y)² = x² + y²+2xy

X+1/x+2.x.1/x = 16

X+1/x = 16-2 = 14

(X+1/x)² = (14)²

Repeating same formula

X² + 1/x² = 196 – 2 = 194

8). Answer: D

Tan 30° .cot 30° + sin 30° . cos 60° – cosec 90°

1/√3 .√3 + 1/2. 1/2 – 1 = 1+ 1/4  − 1 = ¼

9). Answer: A

Area of Triangle = ½ × base ×Height

132 = 1/2 × base × 11

Base = (132 ×2)/11 = 12×2 = 24

10). Answer: B

4_×1         4_×1.5      6_×2         12_×2.5    3_0×3       90_×3.5    315
