b) 875

c) 700

d) 800

Answers :

1). Answer: d)

Let x = 1

6x²+12x = 6x (x+2)

=6(1) (1+2)

= 6×3 = 18

So the number is divisible by both 6 and 18

2). Answer: a)

Substitute p = 2 in 3^p – p + 3

=3²-2+3=10

10 is not a prime number, Answer = 2

3). Answer: b)

LCM of 24, 27 and 30 = 1080

Greatest 4 digit number= 9999

On dividing 9999 by 1080, Remainder=279

Required number= 9999 – 279 = 9720

4). Answer: c)

5). Answer: d)

“If in a given number, the total number of digits are n and if n is even, then square root of that number will have n/2 digits and if n is odd, then number of digits will be (n+1)/2”

For 16451136

Number of digits = 8 and 8 is a even number

Number of digits in Square root= 8/2=4

For 1838736

Number of digits = 7 and 7 is a odd number

Number of digits in Square root = (7+1)/2 = 4

6). Answer: d)

7). Answer: a)

a – b = 2

ab = 35

a³ – b³= (a – b)³ + 3ab(a – b)

= (2)³ + 3(35) × (2)

= 218

8). Answer: c)

Total weight increased= 5×5 = 25 kg

Weight of new person = 90+25 = 115 kg

9). Answer: a)

10). Answer: b)

Let Total profit = 7x

Profit of A = 5x

Profit of B = Profit of C = 1x

5x – 1x = 4x

4x —- 500

7x —— ?

x = 500×7x/4x = 875
