An amount of Rs. 45,000 becomes Rs. 75,375 on simple interest in 9 years. What is the rate of interest p.c.p.a?1). 72). 7.53). 84). 10.5

Answer»

<P>S.I = AMOUNT – Principal

= 75375 – 45000

= RS 30375

$(S.I.\; = \frac{{P \times R \times T}}{{100}})$

Where,

S.I. = Simple Interest

P= Principal

T = Time

R = Rate of interest

∴ $(30375\; = \frac{{45000 \times R \times 9}}{{100}})$

⇒ $(R = \frac{{30375 \times 100}}{{45000 \times 9}})$

⇒ R = 7.5%
