Question

The ages of Vishag and maria are in the ratio 5:7.Four years later the sum of their ages will be 56 years. What are their present ages.

Answer 1

Answer:

Let age be 5x and 7x

(5x + 4 )+ (7x + 4 ) = 56

12x + 8 = 56

12x = 56 - 8

12x = 48

x = 48/12 = 4

Present age of

Vishag is 5 * 4 = 20 years

Maria is 7 * 4 = 28 years

Answer 2

Answer:

I HOPE THIS HELPS YOU

Step-by-step explanation:

RATIO OF THIER AGES = 5:7

LET VISHAG'S PRESENT AGE BE 5x

LET MARIA'S PRESENT AGE BE 7x

4  YEARS LATER :

VISHAG'S AGE = 5x+4

MARIA'S AGE = 7x+4

SUM OF THIER AGES = 5x + 4 + 7x + 4

BUT, AFTER  4 YEARS SUM OF THIER AGES IS 56 YEARS,

SO,

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 56 - 8

12x = 48

x = 48/12

x = 4

Vishag's present age = 5x = 5 × 4 = 20 years

Maria's present age = 7x = 7 × 4 = 28 years
