Question

2.
At what rate of simple interest will Rs. 800 amount to Rs. 836 in 9
months.


​

Answer 1

SI = AMOUNT - PRINCIPAL

= 836-800

= Rs 36

Time = 9/12 months = 3/4 years

Rate = (SI × 100)/(PRINCIPAL × TIME)

= (36×100×4)/(800×3)

= 6%

Answer 2

Answer:

6%

Step-by-step explanation:

Given:

Principle=Rs.800

Amount=Rs. 836

Simple interest=Amount- Principle

=836-800

=Rs. 36

We know that ,

Simple interest=PTR/100

36=800×9/12×R/100

36=72/12×R

R=36/6

R=6%
