at a certain rate of simple interest rupees 40 50 amount to rupees 457 6.50 in 2 years at the same rate of simple interest how much would rupees 100000 amount to in 3 years​

Answer 1

Amount=4576.50

Principal =4050

Rate =r

Time= 2 years

S.I. =526.50

Formula = S.I. =P×R×T÷100

526.50 = 4050×2×r÷100

526.50 = 81r

r = 526.50÷81

r = 6.5%

S.I. when

P = 10000

R = 6.5%

T = 3 years

S.I. = 10000×6.5×3÷100

S.I. = 100×65×3

S.I. =195×100

S.I. =19500. Ans

Answer = 19500
