Medium Open in App Solution Verified by Toppr

Correct option is A)

C.I. for the third year = Rs. 1,452.

C.I. for the second year = Rs. 1,320

∴ S.I on Rs. 1,320 for one year = Rs. 1,452− Rs. 1,320= Rs. 132.

Rate of interest = 1,320 132×100 ​ =10%.

Let the original money be Rs. P.

Amount after 2 year − amount after one year =C.I. for second year.

P(1+ 100 10 ​ ) 2 −P(1+ 100 10 ​ )=1,320 P[( 100 110 ​ ) 2 − 100 110 ​ ]=1,320 ⇒P[( 10 11 ​ ) 2 − 10 11 ​ ]=1,320⇒P( 100 121 ​ − 10 11 ​ )= Rs. 1,320 ⇒P× 100 11 ​ =Rs.1,320⇒P= 11 1,320×100 ​ = Rs. 12,000

∴ Rate of interest =10%

and Original sum of money = Rs. 12,000

Let the sum be P

The sum amounts to Rs. 2800 in 2 years and Rs. 3250 in 5 years.

Simple interest for 3 years = 3250 – 2800 = Rs. 450

⇒ Simple interest for 1 year = 450/3 =  Rs. 150

⇒ Simple interest for 2 years = 2 × 150 = Rs. 300

The sum P = 2800 – 300 = Rs. 2500

P = 2500, t = 1, SI = 150 and r = ?

As we know, SI = Prt/100

⇒ 150 = (2500 × r × 1)/100

⇒ r = (150 × 100)/2500

∴ r = 6%

Interest for 1 year is the same whether it's simple interest or the compound interest.

Now interest of third year = 8575 - 7350 = 1225; means principal for this interest is 7350 if comound interest is takenIf 7350 is the principal interest = 1225

if 100 is the principal interest=(1225/7350)*100 =50/3%

When a thing increases for two successive times the overall increase on initial amount = a + b + (a * b)/100

Therefore overall interest for two years = 50/3 + 50/3 + [(50/3)*(50/3)]/100 = 325/9 %

Therefore amount after 2 years = 100 + 325/9 = 1225/9

If 1225/9 is the amount principal =100

if 7350 is the Sponsored by Aspose

If a certain sum of money amounts to Rs. 1008 in 2 years and to Rs.1164 in 7/2 years, how do you find the sum and the rate of interest?

Interest in 1.5 years = Rs (1164–1008) =Rs 156 Therefore, interest in 1 year = 156/ 1.5 = Rs 104 which means the interest in 2 years = Rs 104*2 =Rs 208.

Sum= amount in 2 years - interest in 2 years

=> sum= 1008- 208

Thus, sum is Rs 800.

Rate= (interest * 100) / sum * time

=> rate = ( 208*100) /800*2

=> rate = 208/16 = 13

Rate is 13%. Anand Prakash

A certain sum amounts to Rs. 7,000 in 2 years and Rs. 8,500 in 3 years. What is the sum and rate percent?

Let S=sum, Rate=r℅.

7000=S(1+r/100)^2…..(1).

8.500=S(1+r/100)^3…..(2).

By (2)÷(1).

(1+r/100)=85/70 =17/14.

r/100=3/14. So, r=150/7 =21.42℅.

From (1), 7000=S(1+0.21)^2.

7000=S*1.4641. So, S=7000/1.46=Rs4794.5 (Approx).

A sum of Rs. 8000 will amount to Rs. 8820 in 2 years if the interest is calculated every year. What is the rate of compound interest?

Answer = 5%

5% of 8000rs = 400rs

so next year amount will be 8400rs and interest on 8400rs is

5% of 8400 = 420rs

So total amount after two years :- 8000+400+420 = 8820rs

you can use this formula to find monthly compound interest.
