Question

what principal will amount to rupees 9744 in 2 years if the rate of interest for successive years at 15% and 20% respectively​

Answer 1

Answer:

7217.77

Step-by-step explanation:

let principle be P

then,

amount = principle + simple intrest

hence

9744 = P + (p×15×1/100) + (p×20×1/100)

=> 9744 = P + (15p/100 + 20p/100)

=> 9744 = P + 35p/100

=> 9744 × 100 = 100p + 35p

=> 974400 = 135p

=> P = 974400/135

=> P = ₹7217.77
