The annual rate of interest per year is 8%
<u>Solution:</u>
Given:- Principal (p) = 4600 rupees, Time –Period (t) = 5 years, Total amount(A) = 6440 rupees
First we will calculate the Interest and then using formula of simple interest we will calculate the rate of interest
Interest = Amount – Principal
Interest = 6440 – 4600 = 1840
Now using the formula of simple Interest and on putting values we get,

Where "P" is the principal and "R" is the rate of interest per annum and "T" is the time period


Hence, the required rate of interest per year is 8%
2^6 is the answer. Multiply the rules because it’s a rule
<h3>Answer:</h3>
[B] O.
[D] H.
[E] X.
<h3>Explanation:</h3>
"<u>Letters such as H and X also have two lines of Symmetry as it can be symmetrically equally divided by two types. The letter O is unique because it has an infinite number of lines of symmetry. If it is folded over on any diagonal, the two halves of the letter are congruent mirror images</u>."
