Question 61

One-third of Poojitha’s age three years ago plus one-half of her age two years from now is twenty years. How old is she now?

Solution

Let her present age is '$$x$$' years.

now according to given question, we will get

$$(1/3)*(x-3)+(1/2)*(x+2)=20$$

$$2(x-3)+3(x+2)=20*6$$

$$2x-6+3x+6=120$$

$$5x=120$$

$$x=24$$

Thus, she is $$24$$years old now.
