Two numbers add up to 247 and the first is 27 bigger than the second. what are the two numbers?

x + y = 247  

x + (x + 27) = 247  

x + y = 247  

2x +27 = 247  

x + y = 247  

2x = 247 - 27 or 227  

x + y = 247  

2x = 220  

x + y = 247  

x = 110  

110 + y = 247  

y = 137  

110 + 137 = 237

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
