P × 8 × 5/2 = 100 { 3180-P}

P×20 = 318000 -100P

120P = 318000

P = 2650

Step-by-step explanation:

GIVEN

• Amount = 3180 ₹

• Time = 2 ¹/2

• Rate = 8%

TO FIND

SOLUTION:-

${ \purple{\boxed{ \sf{principal = \frac{100 \times interest}{rate \times time}}}}}$

$\implies{ \bold{ principal = \frac{100 \times 3180}{8 \times \frac{5}{2} }}}$

$\implies{ \bold{ principal = \frac{318000}{20}}}$

$\implies{ \bold{principal = 15900}}$
