30 men can reap a field in 16 days. How many men will be required to reap another field which is triple in size, within 15 days.​

Answer 1

Step-by-step explanation:

At least 8 colleges across Bengal have suffered on account of an alleged cyber prank that saw their admission merit lists manipulated to reflect names of famous personalities

Answer 2

Answer:

Step-by-step explanation:

We know that the formula of the Man-Days is given by,

[M1 * D1] / [W1] = [M2 * D2] / [W2]  

Here we have,

M1 = No. of men = 30

D1 = No. of days = 16 days

D2 = No. of days = 15 days

W1 & W2 = work done  

M2 = No. of men = need to find?

It is given that the work done by M2 is triple the work done by M1 i.e.,

W2 = 3*W1

⇒ W2/W1 = 3/1  

Therefore, by substituting the given values  

[30*16] / [1] = [M2 * 15] / [3]

⇒ M2 = [30 * 16 * 3] / 15

⇒ M2 = 96  ← men will be required to reap the triple size field within 15 days
