Q:

HCF of 1, 2, 3?

 A) 3 B) 2 C) 1 D) 0

Explanation:

Given numbers are 1, 2 and 3

Factors of 1 = 1

Factors of 2 = 1, 2

Factors of 3 = 1, 2 and 3

Common factors = 1

Hence, the HCF of 1, 2 and 3 = 1.

Q:

A natural number when increased by 12 equals 160 times its reciprocal. Find the number?

 A) 20 B) 12 C) 8 D) 4

Explanation:

Let the required number be 'p'.

From the given data,

p + 12 = 160 x 1/p

=> p + 12 = 160/p

=> p(p + 12) = 160

=> P^2 + 12p - 160 = 0

=> p^2 + 20p - 8p - 160 = 0

=> P(p + 20) - 8(p + 20) = 0

=> (p + 20)(p - 8) = 0

=> p = -20 or p = 8

As, given the number is a natural number, so it can't be negative.

Hence, the required number p = 8.

Q:

10+10(9) =

 A) 180 B) 110 C) 100 D) 19

Explanation:

According to BODMAS Rule,

10 + 10(9)

= 10 + 90

= 100

Q:

The difference of squares of two numbers is 180. The square of the smaller number is 8 times the larger number. Find two numbers.

 A) 10 & 12 B) 10 & 18 C) 12 & -18 D) -12 & 18

Explanation:

Given, difference of the squares of two numbers is 180.

k2 - l2 - 180

Also, square of the smaller number is 8 times the larger.

= l= 8k

Thus, k2 - 8a - 180 = 0

k2 – 18k + 10k - 180 = 0

→  k(k - 18) + 10(k – 18) = 0

= (k + 10)(k – 18) = 0

→  k = -10, 18

Thus, the other number is

324 - 180 = l2

→ Numbers are 12, 18 or -12, 18.
