Qs. 4) A father divide Rs. 1.301
between his sons – Bhavya and
Aakash. He asked them to
invest it at 4% rate of interest
compounded annually. It was
seen that Bhavya and Aakash
got the same amount after 11
and 13 years respectively. How
much did father gave to
Bhavya?
Answer:
Let the two parts be Rs. x and Rs. (1301 – x).
x(1+4100)7=(1301−x)(1+4100)9
x(1301−x)=(1+4100)2=(2625*2526)
=> 625x=676(1301-x)
1301x=676 x 1301x=676.
So,the parts are rs.676 and rs.(1301-676)i.e rs.676 and rs.625
