# A bank gives 5% simple interest per annum. In the bank, Dipubabu deposits₹ 15,000 at the beginning of the year, but withdraws ₹3000 after 3 months and then again, ater 3 months he deposits ₹8000. Let us determine the amount (Principalalong with interest) Dipubabu will get at the end of the year.

Answer :

P = Rs. 15000, r = 5, t = yr and I = ?

Since,

Amount = Principal + Interest

Amount = 15000 + 187.5 = Rs. 15187.5

But, after 3 months Dipubabu withdraws Rs. 3000

So, remain amount in the bank = 15187.5 – 3000 = Rs. 12187.5

P = Rs. 12187.5, r = 5, t = yr and I = ?

Since,

⇒ I = Rs. 152.34

Amount = Principal + Interest

Amount = 12187.5 + 152.34 = Rs. 12339.84

But, after 3 months Dipababu deposits Rs. Rs. 8000

So, amount become in bank = 12339.84 + 8000 = Rs. 20339.84

P = Rs. 20339.84, r = 5, t = and I = ?

Since,

⇒ I = Rs. 508.496

Amount (Principal along with Interest) = Principal + Interest

⇒ Amount = 20339.84 + 508.496 = Rs. 20848.336

Hence, He will get Rs. 20848.336 in the end of year.
