Question

The age of tanay and vihaan are in the ratio of 8:7. Six years later,their ages will be in the ratio 10:9. Find their ages

Answer 1

Ans:

LET THE PRESENT AGES OF TANAY AND VIHAAN BE 8X AND 7X.

SIX YEARS LATER,  

AGE OF TANAY = 8X+6

AGE OF VIHAAN= 7X+6

ACCORDING TO QUESTION

8X+6/ 7X+6= 10/9

9*(8X+6) =10*(7X+6)

= 72X+54= 70X+60

=72X-70X=60-54

2X= 6

X=3

THUS, THE PRESENT AGES OF TANAY AND VIHAAN ARE;

TANAY=8X=24 YRS

VIHAAN=7X=21 YRS

Answer 2

Answer:

Step-by-step explanation:

  age                         tanay                         vihaan

present                       8x                               7x

after 6 years               8x+6                          7x+6

therefore,

8x+6/7x+6 = 10/9

9(8x+6) = 10(7x+6)

72x + 54 = 70x + 60

2x = 6

x = 3

so present age of tanay= 8x = 8×3 = 24

   present age of vihaan = 7x = 7×3 = 21
