5. If Pankaj deposits 1,50,000 rupees
what is the total amount he will get
in
a bank at 10 p.c.p.a. for two years,
from the bank?​

Answer 1

Answer:

The first answer of ₹1200 principal is 104.16% of rate

so, ₹15000 principal for 4 years in 104.16% of rate the interest will be :

interest = (15000*104.16*4) / 100

interest = ₹62,496

5) Amount = P(1 + r/100)n

A = 1,50,000( 1 + 10/100 ) 2

Therefore amount = ₹1,81,500
