Question

The LCM of two prime numbers p and q (p > q) is 221. Find the value of 3p – q.
(a) 4 (b) 28 (c) 38 (d) 48

Answer 1

Answer:

correct

option

is

c) 38

Step-by-step explanation:

3p-q=18

Step-by-step explanation:

LCM of prime no.s is their product

Which means,

p*q=221

factorising 221 we have,

221=13*17

which means the two prime no.s p and q are 17 and 13 respectively(p=17 and q=13 since p>q and 17>13)

3*p - q =3*17-13

51-13

=38
