Let p% of 50 is 2
=> p x 50/100 = 2
=> p = 4%
Hence, 2 is 4 percent of 50.
n (A) = (60/100 * 96) = 288/5, n (B) = (30/100 * 96) = 144/5, n (A ? B) = (15/100 * 96) = 72/5.
n(A ? B) = n (A) + n (B) - n (A ? B) = 72.
So, people who had either or both types of lunch = 72.
Hence, people who had neither type of lunch = (96 - 72)= 24.
1/4 of 12
= 1/4 x 12
= 3
Hence, 1/4 of 12 = 3.
Let the salary of B be 100
Salary of A = 150%
B?s salary less than A = (150-100)/150 X 100 = 100/3 = 33.33%
Let the price of an item be 100After 25% decrease, price of item = 75Increase in price to get the original price = 100-75 = 25% increase to get the original price = 25/75 X 100 = 100/3 = 33.33%
