Answer 1

Answer:

LET THE PRESENT AGE OF MAYANK = X

Step-by-step explanation:

AGE AFTER 15 YEARS =

PRESENT AGE + 15 = 4 TIMES HIS PRESENT AGE

X + 15 = 4X

15 = 3X

X = 5

HIS PRESENT AGE IS 5 YEARS

B) let the present age of isha = x

so the age of his brother = x + 5

after 4 years the ratio will be 2:3

( x + 4) / ( x + 9) = 2:3

3x + 12 = 2x + 18

x = 6

so isha age is 6 years

and her brother age is x + 5

= 6 + 5 = 11

her brother age is 11 years
