Question

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

Answer 1

Answer:

Reshma is 16 years old now

Step-by-step explanation:

let the present age of reshma be x years

thus

after five years, reshma's age will be (x+5) years

Nine years ago, reshma's age would be (x-9)

ACCORDING TO GIVEN CONDITION

reshma's age after 5 years = 3× (reshma's age nine years ago)

x+5=3(x-9)

x+5=3x-27

(shift -27 to LHS and x to RHS)

5+27=3x-x

32=2x

(shift 2 to LHS)

32/2=x

16=x

therefore reshma's present age is 16 years

Answer 2

Answer:

Let the age of reshma = x

X+5 = 3(x-9)

X+5 =3x-27

5+27=2x

32 = 2x

X=32/2

X=16

Hence, Reshma is 16 years old
