Answer 1

Answer:

4:1, 11:1, 5:2, 7:1 yes this is correct

Answer 2

(a) 1:4 (b) 1:16 (c)3:1 (d) 1:7

10/40 = 1/4 (a)

(b) when risha was 2 years old ,then father age 40 - 8 = 32,

so 2/32 = 1/16

(c)age of father after 20 years = 40 + 20 = 60,

age of risha after 10 years = 10 + 10 = 20

ratio = 60/20= 3:1

(d) age of father = 35 years

age of risha = 10 - 5 = 5 years

ratio= 35/5 = 7:1
