• A. $100$
• B. $120$
• C. $1500$
• D. $150$

Answer 1

Answer: (D)

$150$

From the histogram, the maintenance cost in the year:

$1995-1996$ is Rs. $2000$

$1996-1997$ is Rs. $3000$

$1997-1998$ is Rs. $1500$

$1998-1999$ is Rs. $2500$

$1999-2000$ is Rs. $4850$

$2000-2001$ is Rs. $5000$

$2001-2002$ is Rs. $7200$.

Then, the decreased maintenance cost in the year $2000-2001$ when compared to $1999-2000=5000-4850=150$ rupees.

Hence, option $D$ is correct.
