The difference between the compound interest and simple interest on a certain sum at 10% per annum for 2 years is Rs. 631. Find the sum.
Let the sum be Rs. x. Then,C.I. = x ( 1 + ( 10 /100 ))^2 - x = 21x / 100 ,S.I. = (( x * 10 * 2) / 100) = x / 5(C.I) - (S.I) = ((21x / 100 ) - (x / 5 )) = x / 100( x / 100 ) = 632 * x = 63100.Hence, the sum is Rs.63,100.

An observer 1.6 m tall is 203away from a tower. The angle of elevation from his eye to the top of the tower is 30º. The heights of the tower is:
Draw BE // CD
Then, CE = AB = 1.6 m,
BE = AC =
DEtan30=> DE = tan30 x 203=> DE = 13x203 = 20
Therefore, CD = CE + DE = (1.6 + 20) m = 21.6 m.
