1. Find the HCF of the following numbers: (a) 18,48 (b) 30,42 (c) 18,60 (d) 27,63
(e) 36,84 (1) 34, 102 (g) 70,105,175 (h)91, 112,49
(1) 18,54,81 12,45,75​

ans 30,42

Step-by-step explanation:

1. Find the HCF of the following numbers:

(a) 18,48 (b) 30,42 (c) 18,60 (d) 27,63

(e) 36,84 (1) 34, 102 (g) 70,105,175 (h)91, 112,49

(1) 18,54,81 12,45,75

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
