Answer:
An angle measures 130° more than the measure of its supplementary angle.
Therefore the required angle is (180°-130°)°=50°
<h3>50° is the right answer.</h3>
CP of pen = ₹20
Profit % = 20%
Profit % = profit × 100 / CP
20 = profit × 100 / 20
20 × 20 / 100 = profit
Profit = ₹4
Profit = SP - CP
4 = SP - 20
SP = ₹24
Let new CP be ₹x
Profit % = 25%
SP = ₹24
Profit % = SP - CP
25x / 100 = 24 - x
24x / 100 + x = 24
125x / 100 = 24
5x / 4 = 24
x = 24 × 4 / 5
x = ₹ 19.20
Answer is 823.2 cu.in.
Reason
For the sphere
We know V=4/3 TT r^3
Radius is 3
V=4/3 (3.14) 3^3
V= 4/3 (3.14) 27
V= 113.1 for each sphere
8 spheres x 113.1 = 904.8 cu.in.
For the cubed shaped box
We know v= length x width x height
V= 12 x 12 x 12
V = 1728 cu.in.
Now we take volume of box and subtract volume of spheres to get space filled by packing beads
1728 - 904.8 = 823.2 cu.in.
