Question

Ratio of vijay's age to vivek's is equal to 10:9 if vijay will be 26 years old after 6 years find the present age of vivek

Answer 1

HEY....

LOOK .....

VIJAY'S AGE WILL BE 26 YEARS.....AFTER 6 YEARS.....

VIJAY'S AGE = 20 YRS IN PRESENT....

IN PRESENT .....

VIJAY'S AGE : VIVEK'S AGE = 10:9

LET X BE THE COMMON MULTIPLE OF THIS RATIO .....

SO VIJAY'S AGE / VIVEK'S AGE = 10X/9X

NOW

10X = 20 YRS...

SO X = 20/10

X= 2....

SO 9X = VIVEK'S AGE = 2*9= 18 YRS....

SO VIVEK'S AGE IN PRESENT = 18 YRS....
