Correct Answer - Option 3 : 60 days

**Given: **

Manali and Himali together takes = 30 days

Manali worked for = 16 days

Himali completed the remaining work in = 44 days

**Calculation:**

Let the work done by Manali in 1 day be x

Let the work done by Himali in 1 day be y

∴ x + y = 1/30 ----(i)

⇒ 16x + 44y = 1 ----(ii)

∴ Solving equation (i) and (ii),

⇒ x = 1/60

⇒ y = 1/60

**∴**** Himali can complete the entire work in 60 days.**
