Question
Chinu takes 20 days more and
Diksha takes 6 days more than the number of days taken by both of them working together to complete a piece of work. How many days does Chinu take to complete the same piece of work working alone?Solution
ATQ,
Let x be the number of days taken by both Chinu and Diksha working together. Chinu takes 20 days more than both working together = C= x+20. Diksha takes 6 days more than both working together = D=x+6. The combined work rate equation is 
Solve for x
Cross-multiply and simplify to get x2 = 120, so x ≈ 11. Chinu takes C = x+20 = 11+20 = 31 days.
