Question

Jyoti deposited 15000 in a bank and received Rs 900 as interest for one year. a) How much more money should she deposit in the account to earn an interest of Rs 2250 for one year at the same rate of interest?
b) What will be the interest earned in an year if she deposits Rs 105000?​

Answer 1

Answer:

a) ₹37500

b) ₹6300

Step-by-step explanation:

principal = 15000

interest amount = 900

time = 1

by $\frac{p*r*t}{100} = interest$

    $\frac{15000*r*1}{100} = 900$

    $r = \frac{900*100}{15000}$

    $r = 6$

a)

rate = 6%

time = 1 year

interest = 2250

$\frac{p*6*1}{100} = 2250$

$p = \frac{2250*100}{6}$

$p=37500$

b)

p=105000

r=6

t=1

$\frac{105000*6*1}{100} = interest$

$interest = 1050*6$

$interest = 6300$
