Answer 2

Answer:

It can be observed that these penalties are in an A.P. having first term

as 200 and common difference as 50.

a = 200 and d = 50

Penalty that has to be paid if he has delayed the work by 30 days

= S30

= 15 [400 + 1450]

= 15 (1850)

= 27750

Therefore, the contractor has to pay Rs 27750 as penalty..
