Answer 2

Answer:

SI = PRT/100

$si \: = \frac{5040 \times 9 \times 1}{100 \times 7}$

As the the time is given in months so 7 comes as in the denominator. The zero of 100 and 5040 strikes out and as 504 is divisible by 7 by 72 so it will also strike out..

$si \: = \: \frac{72 \times 9}{10} \\ si = \frac{36 \times 9}{5} \\ si = \frac{324}{5} \\ si = 64.8$

:.

5040 + 64.8=

5104.8Rs.
