Question

P=6000 R=? T= 3.6 I=1155
​

Answer 1

Answer:

R = 5.35% p.a

Step-by-step explanation:

According to the formula for simple interest:

$\frac{PRT}{100} = i$

P×R×T/100 = 1155

so here r (rate) is missing so consider it as 'x'

$\frac{P*R*T}{100} = 1155\\\\\frac{6000*x*3.6}{100} = 1155\\\\x= \frac{1155*100}{6000*3.6} \\\\x=\frac{115500}{21600} \\\\x=\frac{1155}{216} \\\\x = 5.347percent = 5.35 percent$

thus the rate of interest is 5.35 % p.a (approx. 5.347% works too but it's too big)
