Question

In what time will Rs.1600 amount to Rs.1768 at 6 % per annum simple interest ?

Answer 1

Hey...!!!

Principal = Rs 1600
Amount = Rs 1768
So, S.I = amount - principle
= 1768 - 1600
= 168
Rate of interest per annum = 6%

So! Time = (S.I x 100) / ( P x R )
= ( 168 x 100) / ( 1600 x 6)
= 1.75

So, Time = 1.75 years

Hope it helps...!!!

Answer 2

Principal = Rs. 1600
Amount = Rs. 1768
Therefore, Interest = Amount - Principal
= Rs. 1768 - Rs. 1600
= Rs. 168
Again, Rate of interest = 6% per annum
Time = ?
Time = S.I. * 100 / PR
= Rs. 168 * 100 / Rs. 1600 * 6% p.a.
= 16800 / 9600
= 168/96 = 56/32 = 28/16 = 14/8 = 7/4 = 1 3/4
Answer: 1 3/4
