Amit and Ananthu can do a work in 15 days and 25 days respectively. Amit started the work and left after 3 days. Ananthu took over and completed the work. In how many days was the total work completed?
Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
Answer:
23 days
Step-by-step explanation:
Amount of work Amit can do in 1 day = 1/15
Amount of work Ananthu can do in 1 day = 1/25
Let us say that Ananthu worked for ‘x’ days.
Then,
3 × 1/15 + x × 1/25 = 1
1/5 + x/25 = 1
x/25 = 4/5
x = 20
Ananthu worked for 20 days.
So, the work was completed in 23 days.
