Answer 2

Principal = ___

Time = 6 months = $\sf{{\dfrac{1}{2}}}$ years

Rate of interest = 11%

Simple Interest = $660

________________________________

$\sf{S.I = {\dfrac{P.T.R}{100}}}$

$\sf{660= {\dfrac{P×{\dfrac{1}{2}}×11}{100}}}$

________________________________

Switching sides ,

$\sf{\dfrac{P×{\dfrac{1}{2}}×11}{100}} =660$

________________________________

Multiply both sides with 100

$\sf{\dfrac{100~P×{\dfrac{1}{2}}×11}{100}} =660×100$

________________________________

Simplify

$\sf{{\dfrac{11~P}{2}}=66000}$

________________________________

Multiply both side by 2

$\sf{{\dfrac{2×11~P}{2}}=66000×2}$

________________________________

Simplify

$\sf{11~P=132000}$

$\sf{P={\dfrac{132000}{11}}}$

$\sf{\color{olive}{\large{\bold{\underline{\underline{P=12000}}}}}}$
