Question

The ratio oF ages of a and b Are 5:4 the sum of ages after 5 years Is 100 Years then the ages are

Answer 1

Answer:

a=45. b=36

Step-by-step explanation:

let their ages be 5x and 4x

After 5years their age =

• 5x +5
• 4x +5

sum of their ages after 5years = 100years

therefore,

5x+5+4x+5=100

9x+10=100

9x=90

x=9

henceforth,

age of a =5*9

=45

age of b =4*9

= 36

Answer 2

Since the present ages of A and B re in the ratio 5:4,they can be taken as 5×years and 4× years respectively. Also given that (5×-16)/(4×-16) =27/20. Cross multiplying and solving for x,we get x=14.Hence, the present ages of A and B are 70 years 56 years respectively.
