Question

find the simple interest on Rs 1800 at 3 in 1 by 2% per annum for 2 in 1 by 2 years​

Answer 1

Answer:

Simple interest (I) = Rs 157.50

Step-by-step explanation:

Principal (P) = Rs 1800,

Rate of interest (R) = 3½% = 7/2%

Time (T)= 2½ years = 5/2 years

Simple interest = I

$I = \frac{PTR}{100}$

$= \frac{1800\times 7\times 5}{100\times 2\times 2}$

$= Rs\:157.50$

Therefore,

Simple interest (I) = Rs 157.50
