Answer 2

Answer:

75238

Step-by-step explanation:

We know, compound interest = Amount − Principal

Therefore, 3200=P(1+10010)2−P

⇒3200=P(1.1)2−P

⇒1320=1.21P−P

⇒P=0.213200

⇒P= Rs. 15238

Simple interest = 100PRT

⇒12000= 100P×10×2

⇒P=201000×100

⇒P= Rs. 60,000

Sum of the principal =15238+60000= Rs. 75238
