ans. A পায় 10000 টাকা
Let, A gets Tk. x
B gets Tk. (25000 – x)
At the end of two years, the interest A gets Tk. = x $(1+\frac{8}{100})^{2}$- x
= x $(\frac{27}{25})^{2}$ -x
= $\frac{729x}{625}-x$
= $\frac{729x-625x}{625}$ = $\frac{104x}{625}$
And, at the end of two years, the interest B gets = Tk. $\frac{(25000-x)\times 10\times 2}{100}$
= TK $\frac{(25000-X)}{5}$
According to question,
$\frac{(25000-X)}{5}$- $\frac{104x}{625}$ = 1336
=> $\frac{3125000-125x-104x}{625}$
=> 3125000 – 229x = 835000
=> 3125000 – 835000 = 229x
=> 229000 = 229x
x = 10000
Ans. $\frac{21}{50}$
Let, the number of male citizen be = 100
& the number of female citizen be = l00.
Male eligible voter = 100 x 60% = 60.
Female eligible voter = 100 x 70% = 70.
Male voted = 60 x 70% = 42
& Female voted = 70 x 60% = 42.
Fraction of citizen voted = $\frac{42+42}{100+100}$ = $\frac{84}{200}=\frac{21}{50}$
