What amount will be received on a sum 0f Rs. 1750 in 2 1/2 Yr, if the interest is compounded at the rate of 8% pa?

 A) RS.2125 B) RS.2122.85 C) RS.2100 D) RS.2200

 B) RS.2122.85

Given, P = RS. 1750,R = 8%, n = 2 and $$\Large \frac{a}{b}$$ = $$\Large \frac{1}{2}$$

According to the formula,

Amount = $$\Large P \left(1+\frac{R}{100}\right)^{n}\times \left(1+\frac{\frac{a}{b}\times R}{100}\right)$$

= $$\Large 1750 \left(1+\frac{8}{100}\right)^{2}$$ $$\Large \left(1+\frac{1/2\times 8}{100}\right)$$

= 1750$$\Large \left(\frac{27}{25}\right)^{2}\times 26/25$$=$$\Large 1750\times 27/25\times 27/25\times 26/25$$

= RS.2122.848=RS.2122.85
