Question

the simple interest of rupees 200 for 4 years in Rupees 6 at the same rate of interest what will be the simple interest on rupees 800 for 3 years​

Answer 1

Answer:

answer is 18

Step-by-step explanation:

$si = \frac{prt}{100} = 6 = \frac{200 \times 4 \times r}{100} \\ r = \frac{100 \times 6}{200 \times 4} = \frac{3}{4}$

now :-

$si = \frac{800 \times 3 \times 3}{100 \times 4} = 18$
