\bold{rate \: of \: return \times M.V = rate \: of \: dividend \times N.V}rateofreturn×M.V=rateofdividend×N.V
\begin{gathered}i. \: \: \: ⟹ \frac{7.5}{100} \times M.V = \frac{9}{100} \times 100 \\ \\ ⟹M.V = 120. \\ \\ M.V \: of \: a \: share = 120\end{gathered}
i.⟹
100
7.5
×M.V=
100
9
×100
⟹M.V=120.
M.Vofashare=120
\begin{gathered}ii. \: \: \: annual \: income \: on \: 1 \: share = \frac{9}{100} \times 100 = 9 \\ \\ ⟹ \: number \: of \: share \: bought = \frac{total \: number \: of \: income}{annual \: income \: on \: 1 \: share} \\ \\ ⟹ \: \frac{630}{9} = 70 \\ \\ ⟹ \: amount \: to \: be \: invested = 70 \times 120 = 8400\end{gathered}
ii.annualincomeon1share=
100
9
×100=9
⟹numberofsharebought=
annualincomeon1share
totalnumberofincome
⟹
9
630
=70
⟹amounttobeinvested=70×120=8400
