Question

Sudha is twice as old as garima $10$ years ago sudha was three times as old as garima find sudha's present age

Answer 1

Let Garima's age be $x$ years

Sudha's age $=2x$

$10$ years ago,

Garima's age$=x-10$

Sudha's age$=2x-10$

According to the question,

$2x-10=3(x-10)$

$\Rightarrow 2x-10=3x-30$

$\Rightarrow 3x-2x=30-10$

$\therefore x=20$

$\therefore$ Garima's present age is $20$years

Hence, sudha's present age is $=2\times 20=40$ years.
