-87 Pqr, - 29pr​

Answer 1

Answer:

i don't know this answer

Answer 2

Answer:

(1) p is a multiple of 3

We have no information about q and r

Not sufficient

(2) q is a multiple of 4

We have no information about p and r

Not sufficient

Combining 1 and 2 , we get

p*q will be a multiple of 3*4 = 12

But we have no information whether r is an integer or not .

If r is an integer , then the product pqr will be divisible by 12 .

If p=3 , q = 4 and r = 1/12 , then product pqr = 3*4 * (1/12) = 1 , therefore product will not be divisible .
