Answer:

(i) a∗b=a−b

Check commutative is

a∗b=b∗a

a∗b=a−b

b∗a=b−a

Since, a∗b



=b∗a

∗ is not commutative.

Check associative

∗ is associative if

(a∗b)∗c=a∗(b∗c)

(a∗b)∗c=(a−b)

∗

c=(a−b)−c=a−b−c

a∗(b∗c)=a∗(b−c)=a−(b−c)=a−b+c

Since (a∗b)∗c



=a∗(b∗c)

If the​ principal, interest​ rate, or time in a simple interest problem is​ doubled, and the other two quantities remain​ consta
VashaNatasha [74]

In this question we have to find the effect of doubling principal, rate or time .

First we have to check the formula which is

I = P rt

As we see that interest is the product of principal, rate and time. So if any of these three doubles, that is if any of these three is twice of the original value, the interest gets doubled.

SO the correct option is C.
