Solution:

Let money Deposited by mom in the bank = Rs x→ (Principal)

You want an interest of Rs 700.→(S.I)

Rate of interest = 7 % per-annually= \frac{7}{12} Monthly→→(R)

Time =1 month= T

Formula for Simple interest (S.I)

S.I=\frac{P\times R \times T}{100}

\frac{x \times 7 \times 1}{12 \times 100}= 700\\\\ x= 8,40,000

Money that i should deposit in the bank = Rs 8,40,000
