Question

A sum of money amounts to 720 rs in 2 yrs n 783 rs in 3 yrs the rate of interest is ?

Answer 1

S.I. for 1 year = 783 -720 = 63
S.I. for 2 Years =63×2 =126
Therefore, Sum = 720 - 126 = 594
R = (S.I.×100)/P×T
R= (126×100)/(594×2) = (350/33)% = 10.6%
Therefore Rate of interest = 10.6%

Answer 2

Step-by-step explanation:

S. I. FOR 1 YEAR = 783-720= 63

S.I.FOR 2 YEARS=63 × 2=126

THEREFORE,SUM=720-126=594

R={S.1.×100 } / P×T

R=(126×100)/(594×2)=(350/33)%=10.6%

THEREFORE AT THE RATE OF INTEREST = 10.6 %
