Question

Question 3. Two numbers are said to be co-prime if their HCF is 1. Match the Pair of numbers given

in column X with their corresponding properties in Column Y by drawing lines.

Column X Column Y

A. (77, 33) 1. co primes as well as semi primes

B. (75, 88) 2. Neither semiprime nor coprime

C. (69 ,77) 3. semiprime but not coprime

D. (56, 63) 4. coprime but not semiprime
​

Answer 1

Answer:

A. (77,33) 4.coprime but not semiprime

B. (75,88) 1.co prime as well as semi prime

C.(69,77) 3.semi prime but not co prime

D.(56,63) 2.Neither semiprime nor coprime

Answer 2

Answer:

See the explanation.

Step-by-step explanation:

Given,

Two numbers are said to be co-prime if their HCF is 1.

Now matching pairs of numbers given in column X with their corresponding properties in column Y we get:

column X             column Y

A. (77,33)             co-prime but not semiprime.

B. (75,88)             co-prime as well as semiprime

C. (69,77)             semiprime but not co-prime

D. (56,63)            neither semiprime nor co-prime

Hence the answer is given above.
