Question

What sum of money will yield 170.10 as simple interest in 2 years 3 months at 6% per annum?​

Answer 1

Answer:

Step-by-step explanation:

s.i = p × r × t/100 ,

t = 2yr 3 m = 2 3/12 yr= 9/4 yrs

170.10 = p × 6 × 9/4/100

54p/ 4 = 17010

54p = 68040

P = 1260

required Sum = Rs1260 Answer

Answer 2

Here,

I = Rs 170.10

T = 2 years 3 months

R = 6%

Hence,

P = (I × 100) / (R × T)

= Rs (170.10 × 100) / {6 × (9 / 4)}

On calculating further, we get,

= Rs (170.10 × 100 × 4) / (6 × 9)

= Rs (17010 × 4) / (6 × 9)

= Rs (17010 × 2) / (3 × 9)

= Rs 34020 / 27

= Rs 1260
