Q. The sum of the ages of Kaveri and Chetan, 20 years, which will be equal to 2 times their present age. If at present Kaveri is 6 years older than Chetan, then what are their present ages?
Explanation:
Let the present ages of Kaveri and Chetan be x years and y years respectively.
As per the question,
(x+20)+(y+20)=2(x+y)
x+y+40=2x+2y
x+y=40…..(i)
Also,
y+6=x
x–y=6…..(ii)
Solving eqns (i) and (ii), we get
x=23 and y=17
Therefore, Present ages of Kaveri and Chetan is 23 years and 17 years respectively
