Find the principal for the amount of rs 61000 that was paid at the rate of interest 11%per annum for 2 years

$\dagger \underline{\large \: \: {\frak{required \: answer : }}}$

Let the principal be Rs. x

Now , by putting the correct formula :

$\dagger \underline{\large \: \: {\frak{ Principal = \frac{100 \times \: amount }{100} +(R×T)}}}$

$\dagger \underline{\large \: \: {\frak{principal = \frac{100 \times 61000}{100} + (11 + 2) }}}$

$\dagger \underline{\large \: \: {\frak{principal = \frac{6100000}{100} + (11 \times 2) }}}$

$\dagger \underline{\large \: \: {\frak{principal = \frac{6100000}{100} + (22) }}}$

Now we will add 100 with 22 to remove hundred from division .

$\dagger \underline{\large \: \: {\frak{principal = 6100000 + (122) }}}$

Now we will take directly take 122 and 6100000

$\dagger \underline{\large \: \: {\frak{principal = \frac{6100000}{122} }}}$

$\dagger \underline{\large \: \: {\frak{principal = 50,000 }}}$

Hence , principal = Rs 50,000.
