Answer:
7935
Step-by-step explanation:
The required number consists of digits 3,5,7,9.
3 in 843 appears in the units place. In the required number 3 has a value which is ten times that in 843. So in the required number 3 appears in the tens place.
9 in 34629 appears in the units place. In the required number 9 has a value which is hundred times that in 34629. So in the required number 9 appears in the hundreds place.
7 in 4782 appears in the hundreds place. In the required number 7 has a value which is ten times that in 4782. So in the required number 7 appears in the thousands place.
5 is in the remaining place.
So the required number is 7935
I believe the answer is D.
The other answers would not make sense, because we do not know what kind of triangle we are looking at and none of the lines are parallel or perpendicular. Therefore we need two angles. C would not work, because if we knew A or B, we would know that the two angles are supplementary. If we had A, then B is 180-A, and vice versa. We do not need both A and B.

Remember these tips:
=> To turn a
percent into a decimal, move the decimal point 2 places to the left.
4%
means 0.04 , and 50% means 0.5 .
=> To turn a decimal into percent, move
the point 2 places to the right.
0.062 means 6.2% .
=> In
math, whenever you see the word "of", it almost always means "times".
So your 2nd example means
16 = (mystery number) x (64).
Divide each
side by 64 : 16/64 = mystery number = 1/4 = 0.25 .
Move the point 2
places to the right. 0.25 = 25% .</span>
