Question

Find the interest on Rs. 6,500 for 2 1/2 years at 4% p.a. S.I.

Answer 1

Answer:

AMOUNT=SI + PRINCIPAL

Step-by-step explanation:

SI= 6500*2.5*4/100

6500*10/100

65000/100

650

AMOUNT= 650+6500

7150

Answer 2

$Given \: Principal (P) = Rs\:6500 , \\Time (T) = 2\frac{1}{2} \: years = \frac{5}{2} \: years ,\\Rate \:of \: interest (R) = 4\% , Let \: simple \: interest = I$

$\boxed { \pink { I = \frac{PTR}{100}}}$

$I = \frac{ 6500 \times \frac{5}{2}\times 4 }{100} \\= 65 \times 5 \times 2 \\= Rs \: 650$

Therefore.,

$\red {simple \: interest}\green { = Rs\:650 }$
