Answers :

1). Answer: d)

The area of rectangular garden with path

= (120 + 24) × (80 + 24)

= 144 × 104

= 14976 m2

The area of rectangular garden = 120 × 80

= 9600 m2

So, area of path = 14976 – 9600 = 5376 m2

2). Answer: c)

3). Answer: c)

If an equation is divisible by (x2+ 2) then substituting x2= – 2 in that equation must give 0 as a result.

(x3 + 5x2 + 10k + 2x) is divisible by x2 + 2.

x3 + 2x + 5x2 + 10k = 0

x(x2 + 2) + 5(x2 + 2) + 10k – 10 = 0

0 + 0 + 10k – 10 = 0

K=10/10=1

4). Answer: d)

CP                           SP

100  ————— 75(25% loss)

100  —————  110(10 % profit)

If selling price is increased by Rs.35, then cost price = Rs. 100

Originally selling price is increased by Rs. 210, so cost price = Rs. 100 /35 x210 = Rs. 600

5). Answer: d)

Let total journey =  x km

x-(3x/14)-(7x/18)=30

x(126-27-49)/126=30

x=75.6 km

6). Answer: d)

Largest single digit prime number = 7

On dividing 95 by 7 remainder is 4 and the difference of two digits is (9 – 5) = 4

7). Answer: a)

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: a)

(tan460° – sin490°) – 2(tan245° – 3cos0°)2

= [(√3 )4 – (1)4] – 2(1 – 3)2

= (9 – 1) – 2(4)

= 8 – 8 = 0

10). Answer: a)

25×√15625×2+3

=25x125x2+3=6253
