A sum of money amounts to Rs.24310 in 2 years at 1o% p.a. if interest payable half yearly. Find the sum.

Given:

• Amount (A) = ₹ 24310

• Rate of interest (r) = 10 /2= 5% I =5/100=.05

• Time (n) = 2 years ×2 = 4 times

Formula:

P = AL [log A - n x log (1 + i)]

P = AL [log 24310 – 4 x log 1.05]

= AL [4.3858-4 × 0.0212]

= AL [4.3858-.0848]

= AL 4.301

P = 20000. रुपये

Topic : Compound interest

sum of money amounts to Rs.14680 in 3 years @5.5 % p.a. compound interest
Given:
• Amount (A) = ₹14,680
• Rate of interest (r) = 5.5% p.a. = 0.055
• Time (n) = 3 years
• Interest = Compound Interest (compounded annually)
Formula:
Principal = AL [ log Amount - n (log 1 + i)]
P = Al [log 14680 - 3 (log 1.055)
P= Al [4.1668 - 3 × 0.0212]
P= Al 3.1761
P= 1500
