Question

the sum required to earn a monthlyinterest of rs. 1200 at 18% per annum s.i is ?

Answer 1

➡HERE IS YOUR ANSWER⬇

Here, annual interest (I)

= Rs 12×1200

= Rs 14400

Time (T) = 1 year

Rate of interest (R)

= 18 %

Let, the sum = Rs S

We know that :

I = (S×T×R)/100

=> S = (100×I)/(T×R)

= (100×14400)/(1×18)

= 80000

Therefore, the required sum is Rs 80000.
