Question

In 5 years time, Reshma will be three times old as she was 9 years ago. How old is she now...?​

Answer 1

LET RESHMA'S PRESENT AGE BE X

AFTER 5 YEARS SHE WILL BE X + 5

9 YEARS AGO

SHE WAS X - 9

ACCORDING TO THE QUESTION,

X + 5 = 3(X - 9)

X + 5 = 3X - 9

X - 3X = -5 -9

-2X = -14

2X = 14

X = 14 ÷ 2

X = 7 YEARS

Answer 2

Let the present age of Reshma be x years
Her age after 5 years = X+5
Her age 9 years ago = X - 9
X+5 =3(x-9)
X+5 =3x-27
X-3x = - 27 - 5
-2x = - 32
2x =32
X = 32 / 2
X = 16

There fore, Reshma is 16 years now


Hope it's help you.
