Question

Rajni and Mohini deposited ₹3,000 and ₹4000 in a company at the rate of 10% per annum for 3 years and 2 ½ years respectively. Find the difference in the amounts they received.

Answer 1

Step-by-step explanation:

Rajni

p=3000

s=10℅

t=3 year

si =prt/100

=3000×3×10/100

=900

amount=p+I

=3000+900

=3900

Mohini

p=4000

r=10℅

t=2(1/2)=5/2

si=prt/100

=4000×10×5/100×2

=1000

amount=p+I

=4000+1000=5000

difference

5000-3900

=1100

Answer 2

Answer:

Ana - - Rs 1100

Step-by-step explanation:

From the question it is given that,

Money deposited by Rajini = ₹ 3000

Time = 3

Rate = 10%

Then, we know the formula of Simple interest I = (P × R × T)/100

I= (3000× (10) × 3)/100

I = ₹ 900

Amount = P + I

= 3000 + 900

= ₹ 3900

Now,

Money deposited by Mohini = ₹ 4000

Time = 2½ = 5/2

Rate = 10%

Then, we know the formula of Simple interest I = (P × R × T)/100

I= (3000× (10) × (5/2))/100

I = ₹ 1000

Amount = P + I

= 4000 + 1000

= ₹ 5000

The difference of the amounts received by them will be = 5000 – 3900

= ₹1100
