S.I=P*R*T/100₉
8,000=P*R*2/100
8,000*100/2=P*R
P*R=4,00,000             ........(i)


C.I=P(1+R/100)
²  -P
8,800=P((100+R)/100)²  -P
⇒8,800 = P((100+R)²/10,000) - P
⇒8,800 = {P(100+R)² - 10,000P)/10,000
⇒8,800*10,000 = P(10,000+R² + 200R) - 10,000P           [(a+b)² = a² + b² + 2ab]
⇒8,800*10,000 = 10,000P + PR² + 200PR -10,000P
⇒8,800*10,000 = PR²+200PR
Substituting value of P*R,
⇒8,800*10,000 = 4,00,000R+8,00,00,000
⇒8,80,00,000-8,00,00,000 = 4,00,000R
⇒80,00,000 = 4,00,000R
⇒R = 80,00,000/4,00,000
⇒R = 20%
⇒P = Rs. 20,000

plz mark it as the brainliest
Thanq.......is there any shortcut for this qn?
if u want to make the question easier, then you can remove two zeroes from 8800 and 8000 to make them 88 and 80 and then solve the question, and at the end, add to zeroes to the final answer
