Answer:
Question 1 :
To convert a fraction to a percent, first divide the numerator by the denominator. Then multiply the decimal by 100.
Question 2 :
50 - 6 = 44 eggs. This means that 44 eggs were good
100% = 50 eggs
1% = 50 ÷ 100
= 0.5 eggs
44 eggs = 44 ÷ 0.5
= 88%
88% of the eggs were good.
Question 3 :
100% = 250
1% = 250 ÷ 100
= 2.5
35% = 2.5 X 35
= 87. 5
35% of 250 is equal to 87.5.
Question 4 :
Original price of the machine = ₹5200 + ₹375
= ₹5575
100% = ₹5575
1% = ₹5575 ÷ 100
= ₹55.75
₹5200 ÷ ₹55.75 = 93.2735426%
100% - 93.2735426% = 6.7264574%
6.7264574% in 2 decimal places can be written as 6.73%
Therefore, the original cost of the machine was ₹5575, and the shopkeeper faced a loss of 6.73% (rounded off to 2 decimal places).
Question 5 :
Principal = 2125.
