Question

the ration of the ages of anupa and her mother is 3:8. The difference of their ages is 35 years. Find the ratio of their ages after 4 years?​

Answer 1

Answer:

present age of anupa=3x

persent age of her mother=8x

after four years

age of anupa=3x+4

age of her mother =8x+4

According to the condition

age of anupa after four years+35=age of her mother after four years

3x+4+35=8x+4

3x+39=8x+4

39-4=8x - 3x

35=5x

5x=35

x=35÷5

x=7

age of anupa=3x+4=3(7)+4=21+4=25

age of her mother =8x+4=8(7)+4=60

ratio of their ages=25:60=5:12
