Question

what principal will amount to rs 13680 in 1 year 9 months at 8% p.a?​

Answer 1

Answer:

P = ₹ 11,528.09

Step-by-step explanation:

Amount = 13680

Principal = P

Time = $1\frac{9}{12}$ = $1\frac{3}{4}$ = $\frac{7}{3}$

Rate = 8%

Simple Interest = 13680 - P

$13680 - P = \frac{P*8*7}{3*100}$

⇒ ( 13680 - P ) × 300 = 56P

⇒ 41,04,000 - 300P = 56P

⇒ 41,04,000 = 300P + 56P

⇒ 41,04,000 = 356P

⇒ P = ₹ 11,528.09
