Answer 2

FORMULA FOR FINDING RATE% :
=> SI × 100 / P × T

QUESTION :-
At what rate the sum of money will double itself in 2 years
SOLUTION :-
Let principal be 100 .
Then , double itself = (100×2)= 200
SI = A - P
=> 200-100
=> 100
Rate = 100×100/100×2
=> 100/2
=> 50%
hence the required rate% is 50%
