मिनधन १.. 18,900 हुन्छ भन सावा रकम पता लगा

Vladimir [108]

Answer:

Solution given:

principal [P]=P

time [T]=4 years

Rate [R]=13%

compound amount=18900

Simple interest=P-18900

we have

simple interest= $\frac{P*T*R}{100}$

P-18900= $\frac{P*4*13}{100}$

100P-1890000=52P

48P=1890000

P=1890000/48

P=39375

the sum that amounts =Rs 39375
