Answer:
If he delayed the work for 30 days then he must pay a penalty of ₹1,650.
Step-by-step explanation:
We know that,
This forms an Arithmetic Progression (AP)
AP = 200, 250, 300,.......
a = 200
d = a2 - a1 = 250 - 200
d = 50
n = 30
We know that,
a(nth) = a + (n - 1)d
a(30th) = 200 + (30 - 1)(50)
a(30th) = 200 + 29 × 50
a(30th) = 200 + 1450
a(30th) = 1650
Thus, if he delayed the work for 30 days then he must pay a penalty of ₹1,650.
Hope it helped and you understood it........All the best
