Question

The present ages of Anjali and Rakesh are in the ratio 15:8. After 10 years, the ratio of their ages will be 5:3. Find their present ages. Will mark as brainliest

Answer 1

Step-by-step explanation:

ratio = 15:8,anjali: rakesh

let anjali's age be 15x

rakesh's age = 8x

or, 15x/8x

after 10 years ,

anjali's age = 15x+10

rakesh's age = 8x+10

ratio = 15x+10:8x+10

or, 15x+10/8x+10

given ratio = 5:3

or, 5/3

therefore,

15x+10/8x+10=5/3

cross multiplication,

3(15x+10)=5(8x+10)

45x + 30 = 40x + 50

45x - 40x = 50 - 30

5x = 20

x=4

anjali's age = 15x = 15 x 4 = 60

rakesh's age = 8x = 8 x 4 = 32

Answer 2

Answer:

Anjali's age - 60

Rakesh's age - 32
