Question

The simple interest on a certain sum for 3 years at 10% per annum is Rs 829.50. find the sum

Answer 1

The answer is given below :

Time = 3 years
Rate = 10% p.a.
Interest = Rs 829.50

We know that,

Interest = (Sum × Time × Rate)/100

=> 829.50 = (Sum × 3 × 10)/100

=> Sum = (829.50 × 100)/(3 × 10)

=> Sum = 2765

Therefore, the required sum is Rs 2765.

Thank you for your question.

Answer 2

si= rs 829.50
r= 10%
t=3years
p=??
si= p×r×t/100
82950/100=p×10×3/100
82950=30p(100 will be cancel from both side)
82950= 30p
p=82950/30
p=2765rs
