Answer:
5%
Step-by-step explanation:
Total 'halwa' made = 1
Divided into four equal portion = 1/4
Arrival of an unexpected guest = 1/5
By what percentage has each family member's share been reduced:
Change in the sharing proportion:
Previous share ratio - new sharing ratio
(1/4 - 1/5) = (5 - 4) / 20 = 1/20
That means total reduction in the sharing = 1/ 20
Since each member comes contributed equally:
Reduction in each family member's share ;
(1 / 20) ÷ 4
(1 / 20) * 1/4 = 1/ 80
Percentage reduction:
(Reduction / original share) * 100%
[(1/80) ÷ (1/4)] * 100
(1/80 * 4/1) * 100%
(1/20) * 100%
= 5%
Reduction in each family members share = 5%

Square.
A square is a rectangle, so rectangle.
A rectangle is a parallelogram, so parallelogram.
Equilateral.
Also Rhombus.
(I think there may be others but these are the few I know)
I don't understand what you mean by 300 and 70, unless you meant 300/70 (in that case it would be 30/7).
5/10 would be 1/5
8/100 would be 2/25.
the amount they paid includes the price of the two smoothies and tip
since the friends are splitting the bill in 2, then each friend pays only half the amount
each friend pays $ 3.60 each
so the total amount they both paid is 3.60 x 2 = $ 7.20
the cost of one smoothie - $3
therefore the cost of the 2 smoothies - 3 x 2 = $ 6
so they paid 7.20 but the bill was only 6 dollars
so the difference in the 2 amounts is the value of the tip they left
tip = 7.20 - 6 = 1.20
so the percentage of the tip is - tip amount / value of the bill x 100 %
percentage = 1.20 / 6.0 x 100 % = 20 %
they left 20 % of the bill as a tip
