Answer 1

Answer: In 2003 it was more by 77.8×10^9

Step-by-step explanation:

A state governments spent amount in housing scheme in 2001 = ₹7.2 × 10^9

A state governments spent amount in housing scheme in 2003 = ₹8.5 ×10^10

7.2 × 10^9,

8.5 ×10^10 = 85/10 ×10^10= 85× 10^9

So, on comparing as in both a common factor 10^9,

85> 7.2 by (85-7.2=) 77.8

In 2003 it was more by 77.8×10^9
