₹3120 has to be paid if calculated by simple interest

anonymous231: can you explain it in detail answer?

sjayalakshmipap37ns4: Simple Interest = P×R×T/100

naadi2006: why T/100

anonymous231: and what if it is compound interest then ?

naadi2006: i am still confused how did he do that

naadi2006: i remember it now but

anonymous231: it's not T/100 it's whole divided by 100

naadi2006: i am confused because of that half thing in it how to show it in steps

naadi2006: and i am getting it as 720

$\huge\bold\red{Solution :\longrightarrow}$

Given,

Principal (P) = Rs 2400

Rate of interest = 12% p.a.

$\mathsf{Time = 2 \frac{1}{2 } = \frac{5}{2} \: \: years} \\$

Now,

$\mathsf{SI = \frac{P \times R \times T}{100}} \\ \\ \: \: \: \: \: \mathsf{= Rs} \: \: \mathfrak{( \frac{2400 \times 12 \times 5}{100 \times 2} ) }\\ \\ \: \: \: \: \: \mathsf{= Rs} \: \:\mathfrak{ 720}$

$\mathsf{Amount = Principal + SI} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathsf{= Rs }\: \:\mathfrak{ (2400 + 720)} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathsf{= Rs} \: \:\mathfrak{ 3120}$
