The present age of Charu is 2.5 times the present age of Harsh. Had Harsh been two years younger and Charu been 13 years older, Charu's age would have been 3.5 times Harsh's age. What is Harsh's present age ?
Let present age of Harsh = $$x$$ years
=> Present age of Charu = $$2.5x$$ years
Acc to ques,
=> $$2.5x + 13 = 3.5 (x - 2)$$
=> $$2.5x + 13 = 3.5x - 7$$
=> $$3.5x - 2.5x = 13 + 7$$
=> $$x = 20$$ years
