Question

10 per cent!
What principal invested at 5% for 3 months will
yield a simple interest of Rs. 25 ?​

Answer 1

Answer:

principal =2000

Step-by-step explanation:

p=(si×100)/(r×t)=(25×100)/(5×3/12)

=(2500×12)/15=30000/15=2000

Answer 2

MAIN FORMULA =Interest = Principal×Rate×Time

----------------------------------

100

So , let the principal be ' x '

25 = x × 5 × 3/12

---------------------------

100

25 = x × 5 × 3

---------------------

100×12

=>25=x × 15

----------------

1200

25 = x

---------

18

= 25 - 18 = x

= 7 = x
