The ratio between the ages of Kishore & Kabir is 5:3 after 5 years the sum of their ages will be 74 years. What is the present age of Kishore ?
50
45
40
60​

Answer 1

Answer:

let the common ratio is x

so the present age of Kishore is 5x years

and the present age of Kabir is 3x years

after 5 years the age of Kishore is( 5x+5) years

after 5 years the age of Kabir is (3x+5)years

so,

(5x+5)+(3x+5)=74

=> 5x+5+3x+5=74

=> 8x=74-10=64

=> x=64/8=8

present age of Kishore is 5x years=5×8years=40years
