16 \;{2}/{3} \%

per annum for

2 {yr}

and the sum becomes ₹ 196 .

₹ 140
₹ 154
₹ 150
None of these

Solution:

Here,

A=

₹

196, r=16 \;{2}/{3} \%=\;{50}/{3} \%

per annum

n=2 {yr}

∴ \;\; A=P(1+\;{r}/{100})^{n}

⇒ \;\; 196=P(1+\;{50}/{3 × 100})^{n}=P(1+\;{1}/{6})^{2}

⇒ \;\; 196=P ×(\;{7}/{6})^{2}

⇒ \;\; 196=P × \;{49}/{36}

∴ \;\; P=\;{196 × 36}/{49}
