Answer 2

Answer:

hope it helpful for u

Step-by-step explanation:

Given a number A exceeds B by 25% means A is 25% more than B.

Converting the above percentage into the number we have A is equal to B adding to 25100

times of B.

Let, the number B be 100.

Then applying the situations given in the question we have,

Number A = B + 25/100

(times of B)

⇒

Number A = B + 25/100

B

Substituting the value of B as assumed to be 100 we have,

Number A = 100+25

⇒

number A = Rs.125.

Now we have to calculate by what percentage is A more than B.

To do so we first calculate the difference of A and B.

The difference is A – B = Rs. (125-100)

⇒

The difference is A – B = Rs. 25.

Now to calculate the value of percentage by which A more than B.

Or we calculate the value of percentage B which is less than A given by,

Percentage B less than A = 25/125(100%)

Gives a percentage by which B less than A = 20%.

Thus, B is 20% less than A.
