A square is a figure with four equal sides and four right angles.In a square the diagonals bisect at right angles .
In the above given options option A is the right answer.
If the diagonals of any parallelogram are perpendicular then the figure is not necessarily a square.
Diagonals are perpendicular in a rhombus too.
A square and Rhombus both have diagonals that are perpendicular.
So it is not a necessary condition for a parallelogram to be a square .
The other options are right .
So option B is the right option that if diagonals are perpendicular is not sufficient to prove the figure to be a square.

the answer is c
Step-by-step explanation:
This is about conversion of currencies.
<u><em>He spent £25 on the first day.</em></u>
- We are told he had spent £28 over 7 days.
Each day, he spends 50 pence more than the previous day. This means that;
1 pound = 100 pence
Thus, 50 pence = (50 × 1)/100 = £0.5
- If the money he spent on the first day is £x.
- On second day, he would have spent a total of; £(x + 0.5)
- On third day; x + 0.5 + 0.5= x + 1
- On fourth day; x + 1 + 0.5 = x + 1.5
- On fifth day; x + 1.5 + 0.5 = x + 2
- On sixth day; x + 2 + 0.5 = x + 2.5
- On seventh day; x + 2.5 + 0.5 = x + 3
x = 28 - 3
x = £25
