In 150 days  2 teachers deliver 5  lectures

Solution:

Given that,

60 teachers give 60 lectures in 60 days

Find the days taken by 1 teacher

$1\ teacher = \frac{60 }{60 \times 60 } \\\\1\ teacher = \frac{1}{60}\ lecture\ per\ day$

how many days will 2 teachers deliver 5  lectures?

Let "x" be the number of days

$5 = \frac{1}{60} \times x \times 2\\\\x = 5 \times 30\\\\x = 150$

Thus in 150 days  2 teachers deliver 5  lectures
