Let the two parts be Rs. x and Rs. (1301 - x).
=> 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
Correct Answer: Rs.612
Explanation:
Amount
= Rs[7500x(1+4/100)²]

=Rs.8112
C.I
= Rs(8112 - 7500)
=Rs.612
Correct Answer: Rs,6400
Explanation:
The population grew from 3600 to 4800 in 3 years. That is a growth of 1200 on 3600 during three year span.

The rate of growth during the next three years will also be the same.
Therefore, the population will grow from 4800 by = 1600
Hence, the population three years from now will be 4800 + 1600 = 6400
