Question

The age of A and B are in ratio of6:5 10 years from now the ratio of their ages will be 11:10 .Find thier present age​

Answer 1

Answer:

Age of A now = 6x

Age of B now = 5x

Age of A after 10 yrs = 11x

Age of B after 10 yrs = 10x

6x+10=11x

5x+10=10x

10 = 5x

x = 10/5 = 2

Present age of A = 6x = 12 yrs

Present age of B = 5x = 10 yrs

Answer 2

Step-by-step explanation:

let ages of A= 6x and B = 5x

ATQ ,A= 6x + 10 , B= 5x +10

$\frac{6x + 10}{5x + 10} = \frac{11}{10 } \\ \: 60x + 100 \: = 55x + 110 \\ 5x = 10 \\ x = 2$

therefore, present age of A = 6x= 6* 2 = 12 yrs B = 5x = 5*2 = 10yrs
