Detailed Solution

It is given,
The number of houses constructed by housing society = 197
The cost of construction of each house = Rs.450000.
According to distributive property,

a b + a c = a (b + c)

Calculate the cost of constructing 197 such houses:

⇒ 450000 × 197 ⇒ 450000 × (200 − 3) ⇒ 450000 × 200 − 450000 × 3 ⇒ 90000000 − 1350000 ⇒ 88650000

Hence, the cost of 197 such houses is calculated to be Rs.88650000.
Hence option (2) is correct.
