Question

A sum of rs 69300 is to be divided between two boys A and B, 21 and 22 years old respectively in such a way like if there portions be invested at 10%p.a. compound interest, they will reach equal amounts on reaching 24 years age.
i) what is the share of each of the original money?
ii)what will each receive when 24 years old?​

Answer 1

Answer:

Let  A's share be =Rsx

Then, B's share =Rs69,300−x

For A,

N=24−21=3years

P=Rsx

For B,

N=24−22=2years

P=Rs69,300−x

R=10  %

So, A's share be =Rsx=Rs33,000

Then, John's share =Rs69,300−x=Rs36,300

Answer 2

Step-by-step explanation:

Sum = Rs 69300

Let share of boy A be Rs x.

Then share of boy B = Rs (69300 – x)

Age of A = 21 years

∴ Time for investment for A (t1) = (24 – 21) years = 3 yrs

Age of B = 22 years

∴ Time for investment for B (t2) = (24 – 22) years = 2 yrs

Rate (r) = 10% p.a.

Now, principal for A (PA) = share of A = Rs x

Principal for B (PB) = share of B = Rs (69300 – x)
