Question

the amount realised by selling 8% share at 144 of the face value of 2,400 was invested in 6% shares at 96 . what would be the different in annual income?​

Answer 1

$\huge\mathcal\pink{Question:-}$

In the figure, AO = OD and OB = OC. Then

$\huge\mathcal\pink{Answer:-}$

In△AOD&△BCO

=>OD=OC (given)

OA=OB(given)

∠AOD=∠COB (vertically opposite)

=>△AOD≅△BOC

∠OAD=∠OBC(angles corresponding to congruent sides)

[∵ AD & BC make equal angles with the same line AB]

HenceAD∣∣BC
